When searching the directory, I see:

WordPress database error: [The used table type doesn't support FULLTEXT indexes]
SELECT wp_connections.id, MATCH (family_name, first_name, middle_name, last_name, title, organization, department, contact_first_name, contact_last_name, bio, notes) AGAINST ('+test') AS score FROM wp_connections WHERE MATCH (family_name, first_name, middle_name, last_name, title, organization, department, contact_first_name, contact_last_name, bio, notes) AGAINST ('+test' IN BOOLEAN MODE) ORDER BY score

SELECT wp_connections_phone.entry_id, MATCH (number) AGAINST ('+test') AS score FROM wp_connections_phone WHERE MATCH (number) AGAINST ('+test' IN BOOLEAN MODE) ORDER BY score

This is followed by three identical notices:
