Apologies if this is a duplicate reply. The system hasn’t accepted previous submits.

I instead chose to run the __search_by_title_only function only when a user is logged in, which satisfies my requirement.

Here’s the exact code I used:

function __search_by_title_only( $search, $wp_query )
{
global $wpdb;

$q = $wp_query->query_vars;
$n = ! empty( $q[‘exact’] ) ? ” : ‘%’;
$search =
$searchand = ”;
foreach ( (array) $q[‘search_terms’] as $term ) {
$term = esc_sql( like_escape( $term ) );
$search .= “{$searchand}($wpdb->posts.post_title LIKE ‘{$n}{$term}{$n}’)”;
$searchand = ‘ AND ‘;
}
if ( ! empty( $search ) ) {
$search = ” AND ({$search}) “;
}
return $search;

}

// call this function ONLY if user is logged in (e.g. admin, editor)
if ( is_user_logged_in() ) {
add_filter(‘posts_search’, ‘__search_by_title_only’, 500, 2);
}

FYI:
I omitted the “&” from the 2nd parameter because it was throwing errors sitewide: “Parameter 2 to __search_by_title_only( ) expected to be a reference”

Produced errors:
function __search_by_title_only( $search, &$wp_query )

Working:
function __search_by_title_only( $search, $wp_query )
