Dear Sir/Madam,
Greetings for the day!
Query expansion is a critical step in developing a search engine.
Therefore, our team used Lucene as an open source to handle this issue. We
have issues to generate synonyms of the query or get *multi-queries from
one query that carry the same meaning*.
that's a mirror, the "source of truth" is:
svn checkout https://svn.apache.org/repos/asf/lucene/dev/trunk
See:
http://wiki.apache.org/solr/HowToContribute
for lots of pointers on how to check things out, compile, test, set up
an IDE (Eclipse, IntelliJ, Netbeans) etc.
Good luck!
Erick
On Fri,
