title: jQuery dataTables - Clear search on a column
body: <p>Looking at this example, <a href="http://www.datatables.net/examples/api/multi_filter_select.html" rel="nofollow">http://www.datatables.net/examples/api/multi_filter_select.html</a>, which uses columns.search() from the DataTable API, how would you 'clear' the search and show all results again when the user selects 'All' or the empty first option?</p>
