• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach vu) OR (sach va)) dang x hoi. hieu va cao xuc van thanh ve ((su tien) OR (tu tieng)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach vu) OR (sach va)) dang x hoi. hieu va cao xuc van thanh ve ((su tien) or (tu tieng))".
