Rails - Feb 2006 - Ruby + Apache Lucene using XMLRPC?

Please excuse me if this has been answered before.
    
    Is there a "how-to" guide or a walkthrough on integrating Lucene
with ROR  via XMLRPC?
    
    I got Ferret to work but I am worried that it''s not going to be as
scalable.
    
    I highly appreciate your assistance.
    
    Thanks
    Frank

A week or so ago I posted the details of my custom XML-RPC server  
(check the archives for it).  There isn''t one built into Lucene,  
though there are certainly a number of projects that do wrap Lucene  
behind web services of one sort or another including the now  
incubating Solr project.

Ferret may be suitable - only testing (or real world use!) will tell.

Hey Nick,
  Thanks for your reply.
  
  Though I have studied Java quite a bit, it''s been terribly long time 
since I programmed in that language (back in the university days).
  
  I have a few questions:
  What version of Apache are you using?
  How long did it take you to implement Lucene
  Do I need to install TomCat to have it running?
  Why are you using Apache''s XML-RPC server? Isn''t there
XML-RPC functionality with Rails? Just curious.
  
  I will eventually buy Erik Hatcher''s book but want to weigh my
options and get my test project working with Lucene.
  
  
  Thanks for your help

  Do I need Tomcat running for this to work?  Do I have any option of not using
Tomcat?
  Where do I put the XML-RPC server code? 
  Must I install the Apache XML-RPC server? Is the installation reversible?

You don''t need Tomcat. Just a JDK to compile and run.  As you can see,
the
code creates its own webserver on port 8080.

Where do I put the XML-RPC server code?


Anywhere you want your Java code to live.

Must I install the Apache XML-RPC server? Is the installation reversible?


At most you probably need the Apache XMLRPC Jar file(s), and probably the
Lucene Jars to run the server code.  It''s just Java, it won''t
bite :)

For the Web Server I''m running Apache 2.5.x (can''t remember
specific)

Not long at all, maybe a day or two. But, I''ve also been actively
programming in Java for awhile, and still am, so that helps me out a
bit.

No, I wanted to avoid just this situation. I didn''t want a whole
servlet container just for searching.

I''m actually using both. The reason for Apache''s XML-RPC
server is so
that I can directly interact with Lucene through Java and not have to
worry about any cross language issues.

And actually, Rails itself doesn''t have any XML-RPC, but Ruby comes
bundled with both a client and a server, of which only the client is
needed in this case. Incredibly handy, I must say.

Hope this helps!
-Nick

If you go with a straight Java solution for this all your server code
is going just your main program, and thats it (see my blog, what you
see there is all the server code I wrote).

And you need to really ''install'' the server. Its just a simple
JAR
file that your include/reference in your own program.

Thanks Tony for your reply.
  
  So should I install JDK with Netbeans from the following location?
  http://java.sun.com/j2se/1.5.0/download-netbeans-50.html
  
  Any tips or gotcha''s I need to be aware of?
  
  Must the installation be done in a directory accessible over the Internet if I
want Lucene to work?
  
  Thanks

I''m not sure about the internals of Lucene -- you''ll probably
want to check
the docs.

You don''t need netbeans... that''s an IDE... like Eclipse.
Should make your download *much*
smaller. Just the latest version of the JDK should do ya.

Sun''s site can be extremely confusing, so go here:

http://java.sun.com/j2se/1.5.0/download.jsp

and click on the "Download JDK 5.0 Update 6" link below the netbeans
and j2ee sections.

Then, click on the "accept" radio button and then click on one of the
linux downloads.
Being on Red Hat, the RPM would probably do ya just fine.

Just use Hyper Estraier.  http://hyperestraier.sourceforge.net/

* Much easier to setup and access via a simple REST API from Ruby, Java, or
C.
* Easily clusterable with the ability segregate nodes or join them for
combined results.
* Fast as hell.  We use it at the NYC Dept. of Correction to find stuff and
not only does it blow Lucene out of the water even though it''s a
server,
it''s easier to setup--even on windows.
* Gives good results with attributes, vectors, and other goodies included.
* Has a REST interface but you can just use the pure Ruby, Java, or C API to
access it.
  - I''m mentioning this again because it''s the best feature.
* Runs on Windows right out of the box.
* Takes 10 minutes to setup, less on windows.  That''s right, less.  No
JVM.
All fast binary goodness baby.
* You can embed it as a library via Ruby or Java if you want the absolute
fastest.
  - Yes, this means that HE out of the box does local/embedded, remote
distributed, and linkable P2P clustered search infrastructure with minimal
setup for three languages.
* Has a decent web UI for managing an estraier master (that''s the
server
that controls the thing).
* Don''t need to buy an O''Reilly book to figure it out.  Plenty
of code
examples and decent docs considering the author is Japanese (better than
most English speaker''s docs really).
* Supports phrase search, regular expressions, attribute search, and
similarity search with Unicode support.

Only thing I''ve ran into is that OSX people will find that darwin
port''s
version is super old (man those guys need a kick in the ass).  I''m
currently
trying to build it on OSX and should have some instructions for it soon.

Otherwise HE is the freaking bomb for Ruby projects simply because it''s
so
damn easy to access from any language via the rest interface.  And when I
say access I don''t mean just doing searches but also administering the
master servers.

I figure if it''s good enough for half of rails-core and nearly every
other
Rails shop I''ve shown it to then it''s good enough for you
folks to at least
try.

Almost forgot my favorite hidden feature:

* You can get Atom or RSS feeds for search results from the master UI.

Now that''s slick.

Download the one without NetBeans (NetBeans is just an IDE. Do you  
need an IDE for what you''re trying to do? If you do, you can always  
download it later). It comes as a self-extracting executable that you  
run anywhere you like, than you simply set the JAVA_HOME environment  
to the directory where you unpacked it into and add $JAVA_HOME/bin to  
your PATH. If you then type "java -version" it should tell you what  
version you have installed.

It should build cleanly on OSX, just remember to use ''make
mac'' (or
something like that) instead of regular ''make all''.  I think
that
applies to the QDBM
package, too.

Hi Ugo,
  
  Thanks for your reply.
  I have been trying to find the download location to download JDK without
Netbeans but so far I am unsuccessful.
  
  I will keep searching for it.
  I will appreciate if oyu can provide any pointers.
  
  
  Thanks
  Frank

Not sure how much easier it is then the 3 lines of ruby code and 5 or
so of Java to get the two talking.

Lucene is also known for being speedy, and everything I''ve seen tends
to agree with this.

Lucene will do the same giving you full document results back with
waited scroes and the like (I''m probably miss stating something here,
as my ''advanced'' knowledge of Lucene is
lacking)

+1 For HE on this one

So does Lucene/Java (obviously need the JRE installed, 5 mins at best
there)

No JVM.

Following few points seem a bit overfill when all you need is a search
tool. (clustering might be useful for insanly large search (NYC
anything in your case would fit))

Didn''t buy any myself for Lucene, online examples and included
examples with source code were enough for me.

Lucene does the same (not sure on regular expressions, but would be

I''m not bashing HE in anyway as I''ve never used it, but just
trying to
point your (or anyones) "Just use X.." statment is misleading and can
lead to narrow minded descions. While HE may work for you and others,
that doesn''t mean that something else wont fill the role just as
nicely and maybe even better. So why not state, "Why not give X a
try.,," and then follow on with the reasons why YOU like it.

Sorry for the rambling, but thats my 2cents...

Sun''s site can be extremely confusing, so go here:

http://java.sun.com/j2se/1.5.0/download.jsp

and click on the "Download JDK 5.0 Update 6" link below the netbeans
and j2ee sections.

Then, click on the "accept" radio button and then click on one of the
linux downloads.
Being on Red Hat, the RPM would probably do ya just fine.

Zed,
  
  I appreciate you taking the time to reply.
  
  I would love to try HE out but worry that it may not fulfill my  requirements.
I have over 5 GB of data that needs to be indexed and  that''s just the
start. As time goes my data needs will grow. May be for  other projects.
  
  Just curious how big is your database?
  
  Thanks for your help.

http://hyperestraier.sourceforge.net/

* Much easier to setup and access via a simple REST API from Ruby, Java, or
C.

combined results.
* Fast as hell.  We use it at the NYC Dept. of Correction to find stuff and
not only does it blow Lucene out of the water even though it''s a
server,
it''s easier to setup--even on windows.
* Gives good results with attributes, vectors, and other goodies included.
* Has a REST interface but you can just use the pure Ruby, Java, or C API to
access it.
  - I''m mentioning this again because it''s the best feature.
* Runs on Windows right out of the box.
* Takes 10 minutes to setup, less on windows.  That''s right, less.  No
JVM.
All fast binary goodness baby.
* You can embed it as a library via Ruby or Java if you want the absolute
fastest.
  - Yes, this means that HE out of the box does local/embedded, remote
distributed, and linkable P2P clustered search infrastructure with minimal
setup for three languages.
* Has a decent web UI for managing an estraier master (that''s the
server
that controls the thing).
* Don''t need to buy an O''Reilly book to figure it out.  Plenty
of code
examples and decent docs considering the author is Japanese (better than
most English speaker''s docs really).
* Supports phrase search, regular expressions, attribute search, and
similarity search with Unicode support.

Only thing I''ve ran into is that OSX people will find that darwin
port''s
version is super old (man those guys need a kick in the ass).  I''m
currently
trying to build it on OSX and should have some instructions for it soon.

Otherwise HE is the freaking bomb for Ruby projects simply because it''s
so
damn easy to access from any language via the rest interface.  And when I
say access I don''t mean just doing searches but also administering the
master servers.

I figure if it''s good enough for half of rails-core and nearly every
other
Rails shop I''ve shown it to then it''s good enough for you
folks to at least
try.

A week or so ago I posted the details of my custom XML-RPC server  
(check the archives for it).  There isn''t one built into Lucene,  
though there are certainly a number of projects that do wrap Lucene  
behind web services of one sort or another including the now  
incubating Solr project.

Ferret may be suitable - only testing (or real world use!) will tell.

It should build cleanly on OSX, just remember to use ''make
mac'' (or
something like that) instead of regular ''make all''.  I think
that
applies to the QDBM
package, too.

posted the errors I am getting about  my server not  finding the symbols:
  
  "symbol  : class IndexReader

  How do I make Lucene available over a port or start it as a server so it can

Well you''re at least missing the import statements... that''s
why you get "unresolved
symbol" errors.

I can tell you that Vector is java.util.Vector and I think Nick is probably
talking about
the XML-RPC WebServer class.. I think that''s
org.apache.xmlrpc.webserver.WebServer.

So, you''d put:

import java.util.Vector
import org.apache.xmlrpc.webserver.WebServer

at the top of your file (above the "public class ... " line but below
any package
declaration if you have one).

Now all this is probably useless information cuz you don''t know what
goes in the rest of
the "..."''s, but maybe Nick will be along soon. I
don''t think you need anything after the
main method opening line and I would think that what goes in all the indexing
and search
methods would be specific to your case.

My apologies for not being more responsive on this thread.  The Rails  
list is so active that I filter it to a folder and only go through  
the messages when I get a rare few free minutes.

While it is "just Java" and it won''t bite, there certainly is
some
basic learning curve jumps to make.  I''m not sure what you mean by  
"XML-RPC is installed".  To get this to work you will need a JDK and  
two JAR files (the XML-RPC one and the Lucene one), both of which  
will need to be in your classpath (much like the Ruby load path).

Lucene itself does not contain a "server", but the code posted uses  
the Apache XML-RPC library to provide a server.  To compile the  
server, as long as it is a single .java file, you can do something  
like (this is psuedo-code, adapt it to your environment):

	javac -cp lucene-1.4.3.jar:xmlrpc-2.0.jar SearchServer.java

There may be other libraries needed?  I''ve got some other libraries  
in my classpath for other reasons, not sure what dependencies  
xmlrpc-2.0.jar has.  Lucene has no dependencies.

And then you''ll have SearchServer.class which you can run like this:

	java -cp lucene-1.4.3.jar:xmlrpc-2.0.jar:. SearchServer

Again, the command-lines provided are off the cuff and may need some  
tweaking for your environment or package names of the SearchServer  
itself.

Best wishes,
	Erik

Dear Erik,
  
  Many thanks for your reply. I can imagine how "rare" a "few
free minutes" can be and certainly appreciate your assistance.
  
I placed the .jar files for Lucene and XML-RPC in my classpath and tried to
compile the SearchServer.java with:
  
  javac -cp 
/var/java/jdk1.5.0_06/lib/lucene-1.4.3.jar:/var/java/jdk1.5.0_06/lib/xmlrpc-3.0a1.jar:/var/java/jdk1.5.0_06/lib/lucene-core-1.9-rc1.jar
/var/java/development/SearchServer.java
  
  I keep getting the following error:
  -----------------
  /var/java/development/SearchServer.java:55: cannot find symbol
  symbol  : method addHandler(java.lang.String,SearchServer)
  location: class org.apache.xmlrpc.webserver.WebServer
         server.addHandler("$default", new SearchServer
               ^
  1 error
  -----------------
  
  So far my searchServer.java (based on your code) includes:
  
  --------------------------------------
  import java.util.Vector;
  import org.apache.xmlrpc.webserver.WebServer;
  import  org.apache.lucene.index.IndexReader;
  import org.apache.lucene.search.IndexSearcher;
  import org.apache.lucene.store.FSDirectory;
  import org.apache.lucene.store.Directory;
  import java.io.BufferedReader;
  import java.io.InputStreamReader;
  import java.io.FileReader;
  import java.io.IOException;
  import org.apache.lucene.analysis.Analyzer;
  import org.apache.lucene.analysis.standard.StandardAnalyzer;

  import org.apache.lucene.search.Query;
  import org.apache.lucene.search.Hits;
  import org.apache.lucene.queryParser.QueryParser;
  import java.util.Hashtable;
  
  public class SearchServer {
     private IndexReader reader;
     private IndexSearcher searcher;
  
     public SearchServer(Directory directory) throws IOException {
       reader = IndexReader.open(directory);
       searcher = new IndexSearcher(reader);
     }
  
  
     public Hashtable search(Vector constraints, int start, int max)
  throws IOException, ParseException {
       // ...
     }
  
     public static void main(String [] args) {
       String indexPath = args[0];
       int port = 8076;
       if (args.length > 1) {
         port = Integer.valueOf(args[1]).intValue();
       }
  
       try {
         WebServer server = new WebServer(port);
         server.addHandler("$default", new SearchServer
  (FSDirectory.getDirectory(indexPath, false)));
         server.start();
       } catch (Exception e) {
         System.err.println("SearchServer: " + e.toString());
         e.printStackTrace(System.err);
       }
     }
  }
  -------------------------------------------------
  
  Why is it complaining about server.addHandler method? What can I do about it?
  
  
  I wish there was a step by step guide to integrating Rails with Lucene.
  
  
  Thank you very much for your and Ben''s assistance. 
  
  
  
  Thanks
  Frank

You have two different versions of Lucene in your classpath.  Remove  
one of them (I recommend you use 1.9RC1 instead of 1.4.3).   This  
shouldn''t be related to the compilation error you''re
getting...

I just compiled my SearchServer using this command-line (normally I  
use an Ant build file though):

$ javac -cp lib/lucene-core-1.9-rc1-dev.jar:lib/xmlrpc-2.0.jar src/ 
java/org/nines/SearchServer.java

And it compiled just fine.

Erik,
  Thanks for your email.
  
  I removed the duplicate jar file and downloaded xmlrpc-2.0.jar (instead  of v
3) and it compiled without any errors. I guess there is some issue  with
XMLRPC-3? Thank you very much for the tip.
  
  Now I have it compiled, I would like to customize the server and start it so I
can query it.
  
  Do I just put the lucene indexing methods in the searchServer.java? 
  Is there an example code for indexing databases? Any reference /pointers are
highly appreciated.
  
  How do I start the server? I tried java SearchServer.java but it complains
about:
  
  Exception in thread "main" java.lang.NoClassDefFoundError
  
  Thank you so much once again. I obviously owe you ;)
  
  Thanks
  Frank

Hello Erik and Lucene Gurus,
  
  I was able to get the Search Server compiled and was able to fix the  previous
errors by moving SearchServer.java to my lib folder (It wasn''t  working
when I was adding current path to classpath in my .bashrc file.
  
  Now I keep getting the error:
  
  Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException:
0
          at SearchServer.main(SearchServer.java:50)
  
  for the following code:
  ------------
     public static void main(String [] args) {
       String indexPath = args[0];
       int port = 8076;
  
----------
  
  When I hard code the path with the following, the server starts fine.
  String indexPath = "/var/www/html";
  
  My question now is why am I getting the above out of bounds exception  and how
can I correct it? How do I pass the path to my main method?
  
  Thanks
  Frank

Heh, you''re gonna laugh... the args array is command line args! Just
run your class like this:

java SearchServer /var/www/html

assuming that "/var/www/html" was the index path you wanted. That
command line also
assumes that you''ve resolved your library dependencies (those jars you
downloaded) some
way other than adding the classpath option to the command line. Sounds like you
already
figured that part out from your previous email.

Thanks Ben for the rescue.
  
  I can''t believe I didn''t figure it out especially cause PHP
uses a similar args array.
  
  The server compiles and runs but now I keep getting
  
  java.lang.NoClassDefFoundError: org/apache/commons/codec/DecoderException
  
  I downloaded the following file
  wget
http://apache.mirrors.esat.net/java-repository/commons-codec/jars/commons-codec-1.3.jar
  
  and placed it in my class path but to no avail.
  
  The full error when trying to call a test function is :
  
  Exception in thread "Thread-0" java.lang.NoClassDefFoundError:
org/apache/commons/codec/DecoderException
          at org.apache.xmlrpc.XmlRpc.createTypeFactory(XmlRpc.java:238)

          at java.lang.Thread.run(Thread.java:595)
  
  
  Any ideas which dependency I am missing now?
  
  Thanks a zillion
  Frank

Sorry, I forgot to mention that on client side I keep getting the following

End of file reached


Once the test server works, I will be on my way to putting Lucene''s
indexing and searching methods.

I highly appreciate your assistance.

Thanks

Sorry Frank... I''m pretty stumped too. If the commons-codec.jar is on
the classpath, it
should be found. And what really sucks is that you have a "no class
found" for an
*exception*... so even once you fix that, it''ll be throwing an
exception. Well, I guess it
might be catching it too, so maybe that won''t be a big deal.

Hmm, you say you "include the DecoderException class"... you
don''t mean just the .class
file, right? If so, that won''t do any good because the java package
system expects the
classes to be in their appropriate package directory. That''s why they
have jars... jars
are just zip files. You can unzip it and look at the package (i.e. directory)
structure
inside. You might actually take a look inside the commons-codec jar and make
sure it has
DecoderException.

Sorry this is being so difficult.... Erik, you still lurking?

I keep having problems with Ferret on ruby-forum.com. It''s giving me 
stale logfiles, occasional crashes, and exploding index files (from 3 to 
60 MB after adding 3 new documents).

Yes, I''m still lurking and reading infrequently.  Yes, Commons Codec  
is needed on the classpath.  Provide us with the exact command-line  
you''re using to launch and perhaps I can help further, but
we''re
really talking about Java 101 here and it is perhaps abusing this  
list to go into too many details on this when there are a plethora of  
resources online that deal with this type of issue.  No offense  
intended, just trying to direct you to the most appropriate resources  
rather than messaging a list of Rails users that most could not care  
less about Java.

Other than having XML-RPC, Lucene, and Commons Codec''s JAR files on  
the classpath you should be in good shape.  Our production  
SearchServer (different from Nick''s in underlying functionality, but  
the same command-line interface) is launched like this:

java -cp build/nines.jar:lib/lucene-core-1.9-rc1-dev.jar:lib/commons- 
codec-1.3.jar:lib/xmlrpc-2.0.jar
         org.nines.SearchServer <indexdir> [port number]

our nines.jar contains org.nines.SearchServer.

Best of luck with your SearchServer efforts.  Perhaps the free  
codebase for Lucene in Action at http://www.lucenebook.com would help  
you get rolling (lots of instructions on how to get the code running)  
or the book would be the next step for you.  :)

Hey Ben,
  
  Thanks for your reply.
  
  I have searched all over the web and cannot find any reason why I  should be
getting that error. I have tried recompiling with different  versions too but no
luck.
  
  >> Sorry Frank... I''m pretty stumped too.
  >>  If the commons-codec.jar is on the classpath, it   should be found.
And what really sucks is that you have a "no class  found" for an
  *exception*... so even once you fix that, it''ll be throwing an
exception.
  
  
  Yes I have the commons-codec.jar file on the classpath. I am compiling using
the following:
  
  javac -cp 
commons-codec-1.2.jar:/var/java/jdk1.5.0_06/lib/xmlrpc-2.0/xmlrpc-2.0.jar:/var/java/jdk1.5.0_06/lib/xmlrpc-2.0.jar:/var/java/jdk1.5.0_06/lib/lucene-core-1.9-rc1.jar:/var/java/jdk1.5.0_06/lib/commons-codec-1.2.jar
SearchServer.java
  
  
  
  >> Hmm, you say you "include the DecoderException class"...
you don''t mean just the .class >>  file, right?
  
  Sorry for the confusion.  I meant to say I have the  following import
statements:
  
  import org.apache.commons.codec.DecoderException;
  import org.apache.commons.codec.*;
  
  
  >> You can unzip it and look at the package (i.e. directory)  structure 
inside. You might actually take a look inside the  commons-codec jar and make
sure it has  DecoderException.
  
  I unzipped the commons-codec.jar file and can see the DecoderException class:

  I should also point that I have tried both version 1.2 and 1.3 of the  codec
file and that the errors do not happen unless a call is made from  my XML-RPC
client.
  
  
  >> Sorry this is being so difficult.... Erik, you still lurking?
  
  Thank you so much to you, Erik and Nick for your assistance so far. I  would
love to move forward once my test call goes without any error.
  
  
  I am also asking the same question on JGuru forum but so far no luck. If I get
an answer I will post it here.
  
  Thanks again guys.
  
  Frank

Frank,
I ironically enough have been trying to solve the exact same problem
as you and am completely Java illiterate as well. With the help of the
list threads (and Erik''s book), I''ve actually got this working
now on
my development environment (os-x).

I''m using java version "1.4.2_09" and used the following
jars:
lucene-1.4.3.jar
commons-codec-1.3.jar
xmlrpc-2.0.1.jar

I now have ruby performing remote procedure calls to the java like a
charm. Feel free to e-mail me offlist if you are still having
troubles.

Derek

I wanted to let the list know that I have the search server working  now. Thank
you so much for all the off-list replies I received from  members of this great
list offering support.
  
  I have the search server communicating with my ROR project and my indices are 
ready to go.
  
  I bought Erik''s wonderful book which is just amazingly full of
information. Not to mention its 457 pages long.
  
  Erik goes in to a lot of detail about almost everything you will need. 
  
  For e.g., I was thinking about searching multiple fields in Lucene but  after
reading Erik''s thoughts, I decided to combine the information in  a
contents field.
  
  
  My wish list :
  
  I hope Erik updates the book so it doesn''t include deprecated
function calls such as:
  
  Field.UnIndexed (...)
  Field.Text (...)
  
  instead of 
  
  new Field(...)
  
  which causes the Java compiler to issue the following messages on compile (at
least when using Lucene 1.9):
  
  Note: SearchServer.java uses or overrides a deprecated API.
  Note: Recompile with -Xlint:deprecation for details.
  
  Nonetheless, this book is a must-have for any application developer. 
Don''t let the complexity of Java stop you from using Lucene.
    
    My solution to Lucene indexing databases is ready and I am willing to
provide any  help I can about the implementation. Please message me if you would
like sample code (I plan to post it soon on my blog).
  
  Thanks Erik, Ben, Nick  and everyone who offered their help. You guys are a
great help.
  
  Frank

Thanks for the kind words!

This all really depends on what you''re doing and how the user needs  
to interact with the system.  For most general purpose searching  
needs, a user simply wants to enter keywords and find stuff, doesn''t  
want to bother with selecting precise fields to narrow things down.   
So a catch-all "contents" field often is the best way to go (though I
also do this in conjunction with separate fields for the advanced  
cases where constraining more precisely is desired).

Yes, we will be updating the book for the new 2.0 revision of Lucene  
coming out soon.  The book was written for Lucene 1.4.3, and Lucene  
1.9 *just* came out today unofficially, and officially so in the next  
few days.  1.9 is backwards compatible with 1.4.3 and forwards  
compatible with the impending 2.0 release where we will sweep up and  
remove all the deprecated API.  Deprecation warnings in the Lucene  
case are harmless, so no worries with seeing those at all and you  
could turn off those warnings with a compiler switch if you like :)
