Add search criteria

[Andr? Noberto]

Hello guys, i'm trying to make some improvements in vb search engine in my forum and I want to add a new criteria.

Its a boolean value stored in post's table, does anyone know how to help me?

I've looking for something in documentation and analysing classes of vb search, but it's still difficult to understand where I should modify search.php in order to add a new criteria.

Thanks in advance
