Search Postgresql Archives

tsearch 2 query

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There are less than 20,000 records being searched here, but the query takes several minutes.

I know this may not be enough info, but would one suggest I optimize the query or put my attention towards other areas.


SELECT id,date,headline as head,headline(body,q),rank(
vectors,q),timestamp FROM stories,to_tsquery('$query') AS q WHERE vectors @@ q ORDER BY $sort DESC OFFSET $offset LIMIT 20
