I attempted to use the sortable_serialize function from perl, however doesn't seem to exist. The only occurrence of the string "sortable" in the /usr/local/perl/5.10.1/Search/ tree is in the pod in Xapian.pm. What am I doing wrong? use Search::Xapian; ... $doc->add_value(4,sortable_serialize($recdate)); Undefined subroutine &main::sortable_serialize called

Hi guys I've just had a thought about something we do with our search on ReportBuyer.com: we cater for both American and British English in our searches and we have had plans for a while now to implement something that allows users to find 'colour' and 'color', 'tap' and 'faucet' by doing some clever programming. Looking at the Xapian docs, though, it appears

Hello. There are several problems I couldn't find a solution. 1. QueryParser does not perform stemming I am working with PHP5 and use the xapian wrapper written by Daniel M?nard I build a query using parseQuery. Output of the parsed query shows that terms are not stemmed, although a stemmer is set ( see code snippet) # create a XapianDatabase object to search in $db = new

Hello, I am looking for a documentation or an example to use the synonym function. I tried this db.add_synonym("omega","xapain"); and this works by adding the flag FLAG_AUTO_SYNONYMS. If i try to use the db.add_synonym("omega","xapain is search engine "); it fails why? Can xapian use synonym for Abbreviations like MBA => Master of business

I don't know whether this is a BUG or for special purpose... According to the definition of "xapian/queryparser.h", FLAG_AUTO_MULTIWORD_SYNONYMS contains bit of FLAG_AUTO_SYNONYMS . Therefore, long as I set the parse flag with FLAG_AUTO_SYNONYMS, the query parser will automatically activate the function of FLAG_AUTO_MULTIWORD_SYNONYMS. See the below source code part from

Hi, I do not understand the stopword function... I've set the termgenerator like this: $self->{'Stemmer'} = new Search::Xapian::Stem(german2); $self->{'Stopper'} = new Search::Xapian::SimpleStopper(); $self->{'TermGenerator'} = new Search::Xapian::TermGenerator; $self->{'TermGenerator'}->set_stemmer( $self->{'Stemmer'} );

Some languages (e.g. German and Danish) have special letters that are often written using two-letter combinations when the appropriate keyboard or medium is not available: ? = ae ? = ue ? = oe ? = ae ? = oe ? = aa ? = ss (there are undoubtedly far more examples than those) As a user of an index, I would like to be able to search for e.g. "schaefer" and get matches on both

Hi All, I used the OP_NEAR operator for queryparser, and when I searched for "apple store" from my own collection, the query is parsed as "Zappl:(pos=1) NEAR 11 Zstore:(pos=2)" but retrieved nothing. However, if I type in "Apple Store", the query is parsed as Xapian::Query((apple:(pos=1) NEAR 11 store:(pos=2))) and some results are showed. I'm not sure whether

I have an application for synonyms for tags in in notmuch, which means synonym expansion for a particular boolean prefix. I have a vague memory of Olly telling me this doesn't work, but I'm not sure about the details. My higher level goal is to support a kind of indirection with tags, where query tag:foo can really generate tag:bar or tag:fub, depending on some kind of configuration.

Which is the better way to indicating synonyms into a table? But I''d get all those synonyms together to the main table. Althought if is choosed a synonym I''d that it were directed to the object of the main table. I don''t know if a polymorphic association could be helpful in this case. Any help please? ------------- create_table :words do |t| t.string :name t.string

Hi, Using ferret and acts_as_ferret. Great work. Is there a way to define some synonyms (searchable words that would not appear in the texts ? Like stop words, but instead of being removed from query and index, they would be added ;-) Can some synonyms be regexp ? I''d like for instance to have ? (oelig) be equivalent to oe in French. Or maybe an utf8 normalization could achieve

Xapians, I am maintaining about two indexes for my search engines which approximately is each the same size. I would like to share this knowledge with you, since many of you have never seen Xapian index of this size. And of course you can search the index by yourself at - http://myhealthcare.com/ - http://find1friend.com/ I need 2 x 100 million more documents into each index, and I hope it will

Very few people seem to be using synonym in Xapian, I recently found some problems in the use of synonyms. Normally, I think we should not contain any prefix info in synonym table except that 'Z'. For example, I have the following synonyms and prefix info: db.add_synonym("search", "find"); db.add_synonym("Zsearch", "Zfind");

Hi All I was wondering if anyone had a solution for the following problem. I user QueryParser to stem my documents before adding them to a database. During the stemming process I would like to find a way of keeping proper nouns that span two or more words together as a phrase. For example "New York" or "Gordon Brown" or "Prime Minister" get spilt up. I see

Hi I've decided to use xapian because my files table in my mysql database is going to grow very large, and it seems mysql isn't good at full text searching. I'm doing this with the php wrapper by the way. The way my system is set out, each user has their own set of files, and when doing a search it is going to be for a specific user's file (based on file name, title,

I have a xapian-daemon, which can be queried via http. A background-process generated every hour one new index and then remove and create a new symlink to the current database. /path/to/index/20120419010000 /path/to/index/20120419020000 /path/to/index/20120419030000 /path/to/index/default => /path/to/index/20120419030000 So the daemon only check the mtime of /path/to/index/default/iamchert

Thanks, the Centos 6 repos don't have that rpm and the http://xapian.org/download page seems to only cover the XS bindings, if I am reading this correctly: But I was able to remove the rpm packages and compile and install the core and swig from source.
