• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) lang van hoc. hieu ((ve co) OR (te bao)) duc va thanh sinh cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) lang van hoc. hieu ((ve co) or (te bao)) duc va thanh sinh cau treo".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sac ky)) lang van hoc. hieu ((ve co) or (te bao)) duc va thanh sinh cau treo*.
