• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thu ((hang mai) or (hang tai)) hoi. hieu van cam ((dua ban) OR (qua ban)) thanh ca cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu ((hang mai) OR (hang tai)) hoi. hieu van cam ((dua ban) OR (qua ban)) thanh ca cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu ((hang mai) or (hang tai)) hoi. hieu van cam ((dua ban) OR (qua ban)) thanh ca cua te*".
