• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty van ma hoi. ((hieu van) OR (lieu va)) am thuc va danh hai ((cau treo) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty van ma hoi. ((hieu van) or (lieu va)) am thuc va danh hai ((cau treo) OR (cau tren))".
