• If you are trying to use Boolean operators, they must be ALL CAPS: quyen tap ((((nam chien) OR (van chien))) OR (cac thu)) đe co ban va y hoc tieng chuong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "quyen tap ((((nam chien) OR (van chien))) or (cac thu)) đe co ban va y hoc tieng chuong".
