No, it's for data where you're going to be searching in random pieces
of the text.  I think you should look at tsearch2, probably.

Will the full text search indexing help me achive a good speed in searching keywords??? 

If you had any way to enforce bounded searches, it'd be a different
matter: strings with initial matches but an unbound end are fast.
(You can do it the other way, too, by some tricks with reversing the
strings.)


can someone plz ellaborate a little about ways we can enforce bounded searches?. I'm basically trying a simple search
i.e. trying to find name of authors user enters into a interface against the 20 miliions records in my db. Can anyone suggest a good way to perform this kind of search ?.
 

Thanks,
Sumeet.
