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