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