I am trying to match a user inputted search term against two tables: posts and galleries. The problem is the union all clause isn't working. Is there something wrong with my code?

$query = mysql_query("

    SELECT * FROM posts WHERE title LIKE '%$searchTerm%'
        OR author LIKE '%$searchTerm%'
        OR location LIKE '%$searchTerm%'
        OR excerpt LIKE '%$searchTerm%'
        OR content LIKE '%$searchTerm%'

        UNION ALL

    SELECT * FROM galleries WHERE title LIKE '%$searchTerm%'

        ");
