• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((lang van) OR (dang xay)) hoi. hieu ve pham thu ((van thanh) OR (ban thanh)) dai cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((lang van) or (dang xay)) hoi. hieu ve pham thu ((van thanh) OR (ban thanh)) dai cua tuc".
