• Performing a fuzzy search may retrieve terms with similar spellings: theo tiem nang - ((nhanh ban) or (nhanh ba)) cua khong thong ((den toan) OR (den tran)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo tiem nang - ((nhanh ban) OR (nhanh ba)) cua khong thong ((den toan) OR (den tran)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tiem nang - ((nhanh ban) or (nhanh ba)) cua khong thong ((den toan) OR (den tran)) cau".
• Adding a wildcard symbol may retrieve word variants: theo tiem nang - ((nhanh ban) or (nhanh ba)) cua khong thong ((den toan) OR (den tran)) cau*.
