For an example there is a tutor name in the list I want to display his/her current city, his/her profile image etc. So I need to get those values from my city table, address table, tutorImages table.. So anybody can help me to make this query?

Try this it will work:

$q = "SELECT keyword, col, city_name, image_name, tutor_code 
            FROM (
                SELECT tutor_name AS keyword, 'Tutors' AS col, IFNULL(c1.city_name, '') city_name, IFNULL(ti.image_name, '') image_name, tutor_code FROM tutors AS t
                LEFT JOIN address a ON t.address_id = a.address_id
                LEFT JOIN city c1 ON a.city_id = c1.city_id 
                LEFT JOIN tutor_images ti ON t.tutor_id = ti.tutor_id and ti.image_type = 'profile'
                UNION
                SELECT subjects AS keyword, 'Subject' AS col, '' city_name, '' image_name, '' tutor_code FROM subject
                UNION
                SELECT city_name AS keyword, 'City' AS col, '' city_name, '' image_name, '' tutor_code FROM city
                UNION
                SELECT institute_name AS keyword, 'Institute' AS col, '' city_name, '' image_name, '' tutor_code FROM institutes
            ) s
          WHERE keyword LIKE '%$queryString%' 
          LIMIT 10";
