Hi all,

Has anyone come across a solution for faster and powerful search stored procedure in a table that contains more than 500K of records?

I am currently trying to work around with it. All helps are appreciated.

Are you using the tsearch2 full text engine? If not, you're missing
the boat for fast searching text. But you didn't really tell us what
exactly you're searching on, so I'm just guessing.

Hm. No. I am not using tsearch2. I have looked at the documentation, but not sure how it benefits me.

I am searching for text such as mobile numbers and user name in my application.

Any idea of having tseach2 to accommodate different search fields? Way of Implementing it will be helpful too.

Thanks.

create custom parser/dictionary would greatly help you.
see dict_regex, for example,
