I am trying to use a full text index, but it seems to be reindexing on
every query.
The query plan looks fine, but the queries take extremely long (hours
even). I think it is reindexing because it is notifying me that
certain long "words" won't be indexed as you can see below, which is
what it does when I create the index.
=> explain select id from source_listings where
plainto_tsquery('view') @@ to_tsvector('english', full_listing);
QUERY PLAN
--------------------------------------------------------------------------------------------------------
Bitmap Heap Scan on source_listings (cost=1454.88..7445.47
rows=1595 width=4)
Recheck Cond: (plainto_tsquery('view'::text) @@
to_tsvector('english'::regconfig, full_listing))
-> Bitmap Index Scan on kw2_index (cost=0.00..1454.48 rows=1595
width=0)
Index Cond: (plainto_tsquery('view'::text) @@
to_tsvector('english'::regconfig, full_listing))
=> explain analyze select id from source_listings where
plainto_tsquery('view') @@ to_tsvector('english', full_listing);
NOTICE: word is too long to be indexed
DETAIL: Words longer than 2047 characters are ignored.

... it just keeps building a new index until I kill it
