• Performing a fuzzy search may retrieve terms with similar spellings: thuat san y mang ((may hoi) OR (may thoi)). hieu ve bao thuc van minh ((vi cua) or (di cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san y mang ((may hoi) OR (may thoi)). hieu ve bao thuc van minh ((vi cua) OR (di cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san y mang ((may hoi) OR (may thoi)). hieu ve bao thuc van minh ((vi cua) or (di cua)) tre*".
