• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (vu sach)) ly nang ma hoi. hieu ((van cam) or (van cau)) tuc va dang hai hau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ly nang ma hoi. hieu ((van cam) OR (van cau)) tuc va dang hai hau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ly nang ma hoi. hieu ((van cam) or (van cau)) tuc va dang hai hau treo".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) ly nang ma hoi. hieu ((van cam) or (van cau)) tuc va dang hai hau treo*.
