• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang ((x hoi) OR (o hoi)). hieu va cham xuc ((van hanh) or (van anh)) dinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang ((x hoi) OR (o hoi)). hieu va cham xuc ((van hanh) OR (van anh)) dinh cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang ((x hoi) OR (o hoi)). hieu va cham xuc ((van hanh) or (van anh)) dinh cuu tre*".
