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