• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (thuoc sach)) ky nang ma hoa. thi ((van cau) OR (van dau)) luc van anh lai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (thuoc sach)) ky nang ma hoa. thi ((van cau) OR (van dau)) luc van anh lai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (thuoc sach)) ky nang ma hoa. thi ((van cau) OR (van dau)) luc van anh lai cuu tre*".
