• Performing a fuzzy search may retrieve terms with similar spellings: tu ((bach dan) or (cach van)) nang ma hoi. hieu ve cam ((xuc van) OR (duc van)) anh vi su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((bach dan) OR (cach van)) nang ma hoi. hieu ve cam ((xuc van) OR (duc van)) anh vi su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((bach dan) or (cach van)) nang ma hoi. hieu ve cam ((xuc van) OR (duc van)) anh vi su triet*".
