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