• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (so sach)) 2 dang xa hoi. hieu van cam ((tuc va) or (duc va)) thanh ha cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) 2 dang xa hoi. hieu van cam ((tuc va) OR (duc va)) thanh ha cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) 2 dang xa hoi. hieu van cam ((tuc va) or (duc va)) thanh ha cua te".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) 2 dang xa hoi. hieu van cam ((tuc va) or (duc va)) thanh ha cua te*.
