• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky ((lang van) OR (dang van)) hoi. hieu va cham xuc va thanh hai ((cau treo) OR (cau triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky ((lang van) OR (dang van)) hoi. hieu va cham xuc va thanh hai ((cau treo) or (cau triet))".
