Okey, I fixed so that if you search for the string "knight", the $search is equal to whatever number that is used to define knights.

However, it won't only list knights.. since it searched for lvl aswell, so it will search for players with level equal to the number of the vocation.

Is there any way to define search method?

Like, a checkbox.
Search by:
Vocations
Level
Name
Guild

And then the search form.
And it uses different querys depending on what box is checked?
