• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tham ((lang xa) OR (lang ha)) hoi. hieu ((ve phat) OR (v pham)) duc va thanh va hoa viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tham ((lang xa) OR (lang ha)) hoi. hieu ((ve phat) or (v pham)) duc va thanh va hoa viet".
