• Performing a fuzzy search may retrieve terms with similar spellings: thuat song y nang ((ma hoi) or (ma hoa)). hieu ve cao duc manh ((anh via) OR (anh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat song y nang ((ma hoi) OR (ma hoa)). hieu ve cao duc manh ((anh via) OR (anh va)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat song y nang ((ma hoi) or (ma hoa)). hieu ve cao duc manh ((anh via) OR (anh va)) cua tre*".
