search for: synonymer

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 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

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.

All, While attempting to use ActiveRecord against a large database, approx. 1700 tables and 4 million rows, I discovered an inefficiency in oci_adapter.rb. The problem seems to be the SQL being generated to lazy-load the columns metadata. "def columns(table_name, name = nil)" method generates the following SQL: select column_name, data_type, data_default, nullable,

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

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\")"

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

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

Hi, I''ve implemented synonym searching in my rails application but have an idea I''d like to implement but can''t figure out how to do. The idea is that I''d like to give the end user the choice on whether to search for the synonym of a word or not. Preferably by extending the query language to parse a construct similar to ''%word1'' and

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 document only has one word:

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
