• If you are trying to use Boolean operators, they must be ALL CAPS: su ((((sac ky) OR (sai ky))) OR (sach ty)) dang ha hoi. hieu ve cam cuc ban hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((((sac ky) OR (sai ky))) or (sach ty)) dang ha hoi. hieu ve cam cuc ban hanh vai cua tre*".
