• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (chieu xanh)) - thanh trung cua thong truong tinh ((toan tap) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (chieu xanh)) - thanh trung cua thong truong tinh ((toan tap) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (chieu xanh)) - thanh trung cua thong truong tinh ((toan tap) or (toan ban))*.
