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