• Performing a fuzzy search may retrieve terms with similar spellings: ((so sach) OR (so sanh)) kho tang xa hoi. ((hieu ve) or (lieu va)) cam duc va hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (so sanh)) kho tang xa hoi. ((hieu ve) OR (lieu va)) cam duc va hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) OR (so sanh)) kho tang xa hoi. ((hieu ve) or (lieu va)) cam duc va hanh vai cua te*".
