• Performing a fuzzy search may retrieve terms with similar spellings: hoc chieu xanh - hanh ((trong o) OR (trong 2)) nhung tuong dan ((toan cau) or (thanh lap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - hanh ((trong o) OR (trong 2)) nhung tuong dan ((toan cau) OR (thanh lap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - hanh ((trong o) OR (trong 2)) nhung tuong dan ((toan cau) or (thanh lap))".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - hanh ((trong o) OR (trong 2)) nhung tuong dan ((toan cau) or (thanh lap))*.
