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