How can I do a custom search with SSP Datatables Individual column searching?

sergiodatatables

Hi, I'm using the Datatables Server Side with the SSP class, and now I have this plugin that works like a charm with the AJAX table:
https://datatables.net/examples/api/multi_filter.html

But now I want to be able to search in one column this way: Posibility to search < or >, for example >30 (is numeric).

Thanks.
