• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (cac ky)) dang ha hoi. ((hieu ve) OR (hieu va)) cuoc tuc xa tinh ca cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) or (cac ky)) dang ha hoi. ((hieu ve) OR (hieu va)) cuoc tuc xa tinh ca cua tre".
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) or (cac ky)) dang ha hoi. ((hieu ve) OR (hieu va)) cuoc tuc xa tinh ca cua tre*.
