• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y dang xay hoi. hieu ve cam ((duc giao) OR (luoc gia)) thanh ((vi cau) OR (di cau)) treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y dang xay hoi. hieu ve cam ((duc giao) or (luoc gia)) thanh ((vi cau) OR (di cau)) treo".
