• Performing a fuzzy search may retrieve terms with similar spellings: thu sach y quang ((ma hoi) OR (mai hoi)). hieu ve cam ((ac va) or (luc va)) danh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y quang ((ma hoi) OR (mai hoi)). hieu ve cam ((ac va) OR (luc va)) danh di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y quang ((ma hoi) OR (mai hoi)). hieu ve cam ((ac va) or (luc va)) danh di cua te*".
