Thanks to @Pat J i removed the syntax that was causing me problems. For those who are interested, inside the Search Everything plugin, on line 198 – 221 there is the following function:
function se_search_default() {
global $wpdb;
$n = ( isset( $this->query_instance->query_vars['exact'] ) && $this->query_instance->query_vars['exact'] ) ? '' : '%';
$search="";
$seperator="";
$terms = $this->se_get_search_terms();
// if it's not a sentance add other terms
//COMMENT OUT/REMOVE
//$search .= '(';
foreach ( $terms as $term ) {
$search .= $seperator;
$search .= sprintf( "((%s.post_title LIKE '%s%s%s') OR (%s.post_content LIKE '%s%s%s'))", $wpdb->posts, $n, $term, $n, $wpdb->posts, $n, $term, $n );
$seperator=" AND ";
}
//COMMENT OUT/REMOVE
//$search .= ')';
return $search;
}
If you are using the Search Everything plugin on WP 3.7, you will need to edit this function accordingly, or differently if you know better. ( I am merely a beginner ). Many thanks!!
