I want to be able to search a lot of fields using queries that use
ILIKE and unfortunately many of the queries will be using the
'%SOMETHING%' or '%SOMETHING' type clauses. Since indexes are useless
on those I was thinking I could use tsvectors but I can't figure out
how to accomplish this.
One option I have seen reccomended is to create a tsvector field and
concat the various fields into that field as a tsvector. That would
work for general text search but I am not sure how I could query
FIELD1 ILIKE '%SOMETHING%' vs FIELD2 ILIKE '%SOMETHING%' . Would
using hstore help in this case?
I should point out that some of the fields are numbers. I am willing
to deal with those separately by building other indexes for them but
of course a unified approach would be preferable.
Any help would be much appreciated. Thanks.
