When will Postgres's full text search supports phrase match and proximity match?
full-text-search, postgresql
Solution
PostgreSQL 9.6 text search supports phrases now
select
*
from (values
('i heart new york'),
('i hate york new')
) docs(body)
where
to_tsvector(body) @@ phraseto_tsquery('new york')
(1 row retrieved)
or by distance between words:
-- a distance of exactly 2 "hops" between "quick" and "fox"
select
*
from (values
('the quick brown fox'),
('quick brown cute fox')
) docs(body)
where
to_tsvector(body) @@ to_tsquery('quick <2> fox')
(1 row retrieved)
Problem
As of Postgres 8.4 the database fts does not support exact phrase match, nor does it support proximity match if given 2 terms. For example, there is no way to tell Postgres to match on content that have word #1 which is in a specified proximity of word #2. Any one know the plan of Postgres and possibly which version will phrase and proximity match be supported?
