If you want to have sticky posts first in results when they match the search query, just add this code to your theme functions.php
:
add_filter( 'relevanssi_hits_filter', 'rlv_sticky_first' ); function rlv_sticky_first( $hits ) { $sticky = array(); $nonsticky = array(); $sticky_post_ids = get_option( 'sticky_posts' ); foreach( $hits[0] as $hit ) { if ( in_array( $hit->ID, $sticky_post_ids ) ) { $sticky[] = $hit; } else { $nonsticky[] = $hit; } } $hits[0] = array_merge( $sticky, $nonsticky ); return $hits; }
