Bug reference: 14552
Logged by: Bjorn Linder
Email address: bjorn(at)eventmy(dot)com
PostgreSQL version: 9.4.5
Operating system: OS 10.11.6
Description:
Working correctly, no results:
SELECT ts_rank(to_tsvector('lets eat a cat'), ('fat & bat | rat'::tsquery &&
'cat'::tsquery));
ts_rank
---------
1e-20
(1 row)
Should also yield no results:
SELECT ts_rank(to_tsvector('lets eat a fat cat'), ('fat & bat |
rat'::tsquery && 'cat'::tsquery));
ts_rank
-----------
0.0991032
(1 row)
Is this intended behavior? Is there a recommended way to nest AND operators
inside OR operations? The relevant documentation looks to be the same for
newer versions so I'm assuming this behavior hasn't been changed between
versions - let me know. Thanks!
