• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (vu sach)) tai lang ha noi. hieu van cam thu ban thanh ((va va) OR (va van)) thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) tai lang ha noi. hieu van cam thu ban thanh ((va va) OR (va van)) thiet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) tai lang ha noi. hieu van cam thu ban thanh ((va va) OR (va van)) thiet*".
