• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky lang van hoi. hieu ve cham ((xuc ban) OR (duc ban)) 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 hoi. hieu ve cham ((xuc ban) OR (duc ban)) thanh hai ((cau treo) or (cau triet))".
• Adding a wildcard symbol may retrieve word variants: tu sai ky lang van hoi. hieu ve cham ((xuc ban) OR (duc ban)) thanh hai ((cau treo) or (cau triet))*.
