• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chi xanh) OR (chi anh)) - thanh trung cap ((nhung cong) OR (dung cong)) san toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi xanh) OR (chi anh)) - thanh trung cap ((nhung cong) or (dung cong)) san toan tap*".
