jqgrid - search toolbar - jqgrid

Question

The Toolbar Search demo under section 3.7 draws up the search toolbar for every column. Is it possible to have just one search toolbar that filters data across all columns and all pages?
For more info: jqGrid filtering on the client-side using "filterToolbar"
