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