<?php

add_filter( 'facetwp_wpdb_sql', function( $sql, $facet ) {
	if ( 'keywords' == $facet['name'] ) {
		global $wpdb;

        SELECT DISTINCT post_id FROM {$wpdb->prefix}facetwp_index
        WHERE facet_name = %s AND facet_display_value LIKE %s";

		$sql = $wpdb->prepare( $sql, $facet['name'], $selected_values );
