• If you are trying to use Boolean operators, they must be ALL CAPS: tuyen tap ((va kiem) OR (((thi hien) OR (thi lien)))) đe co ban le y thi cong cong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuyen tap ((va kiem) or (((thi hien) OR (thi lien)))) đe co ban le y thi cong cong".
