Hi.
I had a similar problem recently and I found this bit of code that did the trick for me. Here’s a link to the article.
// Make the search to index custom
/**
* Extend WordPress search to include custom fields
* http://adambalee.com
*
* Join posts and postmeta tables
* http://codex.wordpress.org/Plugin_API/Filter_Reference/posts_join
*/
function cf_search_join( $join ) {
global $wpdb;
if ( is_search() ) {
$join .=' LEFT JOIN '.$wpdb->postmeta. ' ON '. $wpdb->posts . '.ID = ' . $wpdb->postmeta . '.post_id ';
}
return $join;
}
add_filter('posts_join', 'cf_search_join' );
/**
* Modify the search query with posts_where
* http://codex.wordpress.org/Plugin_API/Filter_Reference/posts_where
*/
function cf_search_where( $where ) {
global $pagenow, $wpdb;
if ( is_search() ) {
$where = preg_replace(
"/\(\s*".$wpdb->posts.".post_title\s+LIKE\s*(\'[^\']+\')\s*\)/",
"(".$wpdb->posts.".post_title LIKE $1) OR (".$wpdb->postmeta.".meta_value LIKE $1)", $where );
}
return $where;
}
add_filter( 'posts_where', 'cf_search_where' );
/**
* Prevent duplicates
* http://codex.wordpress.org/Plugin_API/Filter_Reference/posts_distinct
*/
function cf_search_distinct( $where ) {
global $wpdb;
if ( is_search() ) {
return "DISTINCT";
}
return $where;
}
add_filter( 'posts_distinct', 'cf_search_distinct' );
