• Performing a fuzzy search may retrieve terms with similar spellings: te sach ly ((nang co) or (nang noi)) hoi. hieu ve canh thuc va ((danh dai) OR (danh sai)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly ((nang co) OR (nang noi)) hoi. hieu ve canh thuc va ((danh dai) OR (danh sai)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly ((nang co) or (nang noi)) hoi. hieu ve canh thuc va ((danh dai) OR (danh sai)) cua te".
• Adding a wildcard symbol may retrieve word variants: te sach ly ((nang co) or (nang noi)) hoi. hieu ve canh thuc va ((danh dai) OR (danh sai)) cua te*.
