Button Filter + Multiple Filter Input (server-side)

Hi all,
in my table i don't have global search input (sSearch) but multiple input for search column (sSearch_0, sSearch_1.... etc) now i need to do a button called "Filter" and when i click on it send the request on controller with all params (sSearch_0=Test, sSearch_1=Test2.... etc) without keyup event on every filter input

how can I do?

Thx a lot
