• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky tang ma hoa. hieu ((van cam) or (van nam)) qua ban thanh vai ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky tang ma hoa. hieu ((van cam) OR (van nam)) qua ban thanh vai ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky tang ma hoa. hieu ((van cam) or (van nam)) qua ban thanh vai ((cuu tre) OR (cau treo))*".
