• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) y ((mang may) or (lang van)) hoi. hieu ve cam tuc va hanh moi cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) y ((mang may) OR (lang van)) hoi. hieu ve cam tuc va hanh moi cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) y ((mang may) or (lang van)) hoi. hieu ve cam tuc va hanh moi cua viet*".
