search for: synonyms

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"); db.add_synonym("foo ba...

...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 I can do this using synonyms although the documentation's not clear on how this works (sorry if this is starting to sound a little annoying). Having dug through the mailing list, I can surmise that: o Synonyms only need to be added to a database once and are transaction-persistent o They're activated by adding...

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...

Oracle should apply the WHERE...

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

Hello, I'm still testing PHP5 bindings and I could'nt find a way to delete all documents from a DB without deleting other informations stored in the DB such as synonyms. Since the process of adding synonyms is time consuming, I would like to use the same DB but restart my test without any document in the DB, is this possibile? I could'nt find a delete_all or a method like that, nor an iterator over all documents without querying. Any idea? -- Alessandro P...

Dear group, There are postings on extracting partial string using sub()/gsub()/gsubfn() but I still couldn't figure this one out. Supposed I am pulling the synonyms of "help" using synonyms("help") from wordnet and get the followings: > synonyms("help") [1] "c(\"aid\", \"assist\", \"assistance\", \"help\")" [2] "c(\"aid\", \"assistance\", \"he...

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? -------------...

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...

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?

...search for the synonym of a word or not. Preferably by extending the query language to parse a construct similar to ''%word1'' and then have the word turned into a or list (i.e., word1|word2|word3|...). Currently, the query parser constantly calls SynonymTokenFilter to get synonyms for each token. Is there a way I can go about achieving this functionality? Here''s an overview of what I''ve done so far: My model classes in my rails app use acts_as_ferret with a call that looks like: acts_as_ferret( :fields => [:body], :store_class_name =>...

Hallo List Users, I am curious if there is a way to rewrite domain name to another domain name. My goal is to provide authentication and mailboxes for the synonymous domains in a single source while keeping all other domains separate. I have setup: auth_username_format = %Lu mail_location = /var/vmail/%d/%u/Maildir in userdb/passdb (passwd-file): /etc/dovecot/%d/users Say I

I am working with version 1.2.7 and want to use stemming and synonyms. I use the perl-bindings and get some problems. First of all: the perl-bindings dont allow the QueryParser a third argument when calling parse_query! So i cannot set a default prefix (which perhaps is the solution to my problem, but later more) i have a simple testcase: 3 documents, every...

Incidentally, if you're actually aiming to match different forms of a name (Peter vs Pete, Ann vs Anne vs Annette) then you might find the synonym feature a better option than wildcarding. You'd need to give it a list of names to treat as synonyms, but it should have many fewer false positives, and can also handle cases which aren't just a substring - e.g. Robert vs Rob vs Bob vs Bobby, or look entirely different: e.g. Terence vs Terrence vs Spike or Margaret vs Peggy vs Daisy.
