only returns 5 products

Hi there,

Here is an example how to change products number to 12 on the search results page:

add_filter( 'loop_shop_per_page', 'ysm_loop_shop_per_page', 20 );
/**
 * Return the number of products you want to show per page.
 */
function ysm_loop_shop_per_page( $cols ) {
	return 12;
}
