/**
 * Apply the same filter to all DataTable instances on a particular page. The
 * function call exactly matches that used by `fnFilter()` so regular expression
 * and individual column sorting can be used.
 *
 * DataTables 1.10+ provides this ability through its new API, which is able to
 * to control multiple tables at a time.
 * `$('.dataTable').DataTable().search( ... )` for example will apply the same
 * filter to all tables on the page. The new API should be used in preference
 * to this older method if at all possible.
