• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sac ky)) nang ((o hai) OR (so hai)). hieu ve cac xuc van anh tai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sac ky)) nang ((o hai) or (so hai)). hieu ve cac xuc van anh tai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sac ky)) nang ((o hai) or (so hai)). hieu ve cac xuc van anh tai cuu tre*.
