• If you are trying to use Boolean operators, they must be ALL CAPS: tuyen tap ((cac thoi) OR (((cach noi) OR (cach thoi)))) đe cao bang ly ky thi cong cong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuyen tap ((cac thoi) or (((cach noi) OR (cach thoi)))) đe cao bang ly ky thi cong cong".
