Tell SearchWP to return results in a random order (as opposed to ordered by relevance)

gistfile1.php

<?php

function my_searchwp_return_orderby_random( $random, $engine ) {
	
	// if it's not the default search engine, have results be random
	if ( 'default' !== $engine ) {
		$random = true;
	}
	
	return $random;
}

add_filter( 'searchwp_return_orderby_random', 'my_searchwp_return_orderby_random', 20, 2 );
