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