• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - manh ((trung tuan) OR (tran tuan)) nhung cong san ((toan cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - manh ((trung tuan) OR (tran tuan)) nhung cong san ((toan cau) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - manh ((trung tuan) OR (tran tuan)) nhung cong san ((toan cau) or (than cap))*.
