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