• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky dang ((((ma hoi) OR (mai hoi))) or (xa hoi)). hieu ve cam xuc va thanh tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky dang ((((ma hoi) OR (mai hoi))) OR (xa hoi)). hieu ve cam xuc va thanh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky dang ((((ma hoi) OR (mai hoi))) or (xa hoi)). hieu ve cam xuc va thanh tai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky dang ((((ma hoi) OR (mai hoi))) or (xa hoi)). hieu ve cam xuc va thanh tai cua tre*.
