similar to: Getting a Lucene.net index readable by Ferret

I found it quite fun to generate index by ferret. However, I had to use lucene now. Can I use the index that I''ve already done by ferret? ps. Lucene 2.2.0 vs Ferret 0.11.4 Thx! -- Posted via http://www.ruby-forum.com/.

We use Nutch and Lucene for our heavy duty text analysis jobs but I?m trying to use ferrret to do some experiments. I understood that Ferret used the same index format as lucene but I cannot look into a lucene index with ferret and cannot read a ferret index with luke (the lucene index browser). Am I doing somehting wrong or have the formats diverged? -------------- next part -------------- An

Hi, I am working on a project which has a large Lucene index in place. Can (any version of) Ferret be used against an index built using Java Lucene? Thanks, Eric

Hi All, Hope all is going well. After being knocked out with the flu for a week I''ve been able to make some progress with porting the lucene highlighter to ferret. I''ve got a draft version available for perusal at: http://crafterm.net/ruby/highlighter/highlighter-ruby-0.1.tar.gz The port is pretty much a complete copy of the Java version at:

I jut noticed this example in the lucene documentation*: title:(+return +"pink panther") I have been using this syntax: +title:(return AND "pink panther") Seemingly with success. Are both acceptable? I couldn''t find any documentation on "the plus sign" itself. Thanks for any pointers. John

I would like to generate a Lucene index in Java (of plain text values only,) and be able to use that index in ferret. I''ve seen many mixed answers to this question, so I''m hoping some of you can help. Thanks! -- Posted via http://www.ruby-forum.com/.

Hi Folks, I''ve just released version 0.9.0. This latest version of Ferret is an alpha release. I have removed the old c extension and Ferret is now running on a fully ported C library. This has allowed some huge performance improvements both with regard to memory and CPU usage. There will probably be a few portability issues to start with. It has been developed on Linux so it should

I haven''t dug into this yet, but wanted to report it. I''ve built an index with Java Lucene (1.9, from svn trunk) and then trying to search it with Ferret and getting this: /usr/lib/ruby/site_ruby/1.8/ferret/index/term_buffer.rb:31:in `read'': undefined method `name'' for nil:NilClass (NoMethodError) from /usr/lib/ruby/site_ruby/1.8/ferret/index/

We''re running Ferret and acts_as_ferret in our production environment. We have multiple mongrels talking to a single index on a separate (virtual) server over DRb. This is working ok for now, as our index updates are fairly infrequent. I''m concerned with the lack of rendundancy/scalability in this layout. Our index won''t get too big - maybe 100k indexed objects, each no

Hello All: This is potentially a ferret and ruby newbie question. I RTFM-ed (the oreilly shortcut anyway) and didnt find anything obvious. Are there plans for Ferret to support the notion of "payloads" introduced in Lucene 2.2. Payloads are basically arbitrary metadata that can be stored for each term. For example, for each term I can store, say, font information for the term. (

Hi all, Having problems trying to get Ferret to read an index generated by Lucene. Am I right in thinking Ferret should be able to read a Lucene generated index no problem? Using the code snippets detailed in http://www.ruby-forum.com/topic/64099#new Any advice gratefully received. Many Thanks, Steven -- Posted via http://www.ruby-forum.com/.

Hi, Does anyone know why the indexes created by Ferret can''t be opened by Luke (http://www.getopt.org/luke/)? When I do development with Clucene I use Luke all the time to understand what is going on in the index. It is especially useful when trying to diagnose analyzer issues. When I try to open a Ferret index with Luke I get the message "Invalid or corrupted index". I

Lucene has a syntax "foo bar"~10 for finding foo within 10 words of bar. Does ferret support this feature? (the ~ is used for fuzzy queries) Does rdig? This could be a deal breaker for me ''cos I really need proximity searches -- Posted via http://www.ruby-forum.com/.

Recently I''ve been revisiting some of my search code. With a greater understanding of how Java Lucene implements its search methods, I realized that one level of abstraction is not present in the Ferret classes/methods. Here are the relevant method signatures: Ferret''s search methods: in Ferret::Index::Index: search(query, options = {}) -> returns a TopDocs

Hi, first of all: great work! I''d like to know which Lucene Version Ferret is based on, in other words: will I be able to read/write indexes created with current lucene trunk ?

Hi, in my person model, I have a enumeration field "role" that take bits like 1, 2, 4, 8, 16, ..... they represent person roles(eg: admin(1), QA(2), manager(4) .... ). Each person can take on multiple roles. say there''s person A that''s both a admin and QA(the role value is "3") so if I search like "Person.find_by_content(''role:(1))", I

We are using Ferret on our site answeru.com. Today all of a sudden we started getting Ferret errors while users were trying to register or log into the system. I am not a Ferret techie - I apologize if a similar problem has already been asked or if it is not really a Ferret issue. Any ideas: IO Error occured at <except.c>:79 in xraise Error occured in fs_store.c:324 - fs_open_input

Hi, I have some questions about the way that documents are scored by the Boolean and MultiTerm Queries, and about possible options for custom scoring articles. I am working on a project experimenting with different methods of automatically generating queries and the scoring mechanisms behind Lucene and Ferret have been perplexing us. >From looking at the Lucene explanation at (

Hi everyone, I''m pretty new to Lucene and Ferret, so I feel that this is most likely myself not completely understanding the correct way to do this. I haved indexed ~2200 text files (of various sizes), and I am now running searches on the index to get a feel for Lucene and Ferret. In my first program, which is using Lucene I search for ''influenza'' and get the
