Just read the docs in contrib/tsearch2 in the PostgreSQL distribution.

I search for particular strings using regular expressions (e.g. where
column ~* $query) through a text data type column which contains notes
(some html code like <b>bold</b> is included).
It works but my question is whether there would be a way to speed up
searches?
From my limited investigation, I see the features "CREATE INDEX" and
"tsearch2" but I'm not clear on how these work, whether they would be
appropriate, and whether there would be a better approach.
I'd appreciate being pointed in the right direction.
