Running 7.0.2 on Alpha/RedHat 6.2 256MB RAM
In order to implement a fulltext search, I have a func that parses list
of words and creates a regexp query with things like [[:<:]]( word |
word | ... )[[:>:]]
That query then is passed to backend...
Now the strange thing:
gamenet=# SELECT id, title,publishdate,categoryid FROM articles WHERE
translate(title,'abcdefghijklmnopqrstuvwxyzâèçìîíïòðûþõäöü','ABCDEFGHIJKLMNOPQRSTUVWXYZÂÈÇÌÎÍÏÒÐÛÞÕÄÖÜ')~
'(BLACK|SERIOUS|SAM)[[:>:]]'::text; id | title | publishdate | categoryid

It seems that if the regexp is too complex (more than 3 |-ed
elements) it doesnt return.
Any ideas?
