Update to show results by catefory?

Ok so i found your sample filters ?? Just not sure why they wont work when placed in my functions file? Any specific place these should live?

OK so i did a little hacking and this works well – obviously can be expanded:

Add this to class-daves-wordpress-live-search-results.php line 163:

apply_filters( 'dwls_alter_search', $query, -1 );

Then add this to your functions.php:

//update for daves search to add a cat filter
function search_only_cat($query)
{
 $query->set('cat', '2');//this can be numerous cats ie. 2,3,4
}
add_action('dwls_alter_search', 'search_only_cat');
