Would it be possible without writing a very long tsquery to exploit the index to retrieve the tsvectors that contain at least N lexemes?
If not exploiting the index... any suggestion to improve performance of such a query? computing rank still requires retrieving a lot of tsvectors and compute the rank for each of them. -- Ivan Sergio Borgonovo http://www.webthatworks.it -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
