Re: Incorrect FTS result with GIN index

I tested the same backup on our CentOS 5.4 virtual machine (running on xen
server) and the results are really weird (118 rows, comparing to 116 on win
xp and 123 expected):

Aggregate (cost=104.00..104.01 rows=1 width=0) (actual
time=120.373..120.374 rows=1 loops=1)
-> Bitmap Heap Scan on search_tab (cost=5.35..103.93 rows=25 width=0)
(actual time=59.418..120.137 rows=118 loops=1)
Recheck Cond: ((to_tsvector('german'::regconfig, keywords) @@
'''ee'':*'::tsquery) AND (to_tsvector('german'::regconfig, keywords) @@
'''dd'':*'::tsquery))
-> Bitmap Index Scan on idx_keywords_ger (cost=0.00..5.34 rows=25
width=0) (actual time=59.229..59.229 rows=495 loops=1)
Index Cond: ((to_tsvector('german'::regconfig, keywords) @@
'''ee'':*'::tsquery) AND (to_tsvector('german'::regconfig, keywords) @@
'''dd'':*'::tsquery))
Total runtime: 120.670 ms

And here are the configuration details:
