Adding a thank you field to members search

[HS2005]

Dear vb,

>> In memberlist.php?do=search you can put in a number while looking for example:
Post Count
is Greater than or Equal to | is Less than

>> I want to search for members who's thanks you count is greater than or Equal to | is Less than.

>> I was wondering how i can add a search field while searching for members.

And i mean from the hack: Post thank you hack.
I already made the fields but dunno how to put the name to search for.
Thanks.
