Jquery DataTable filtering without using a global object

I have a datatable that is sometimes shown and sometimes hidden. I also have several other tables on the same page.

The datatables example (located here) uses a global object to store your custom function $.fn.dataTable.ext.search. This is great, it affects all tables.

I can't find a way to provide a search function per table and not add it to a global variable.
