• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu tinh)) - thanh trung ((chap thuong) OR (pham thuong)) cong tac toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu tinh)) - thanh trung ((chap thuong) OR (pham thuong)) cong tac toan tap*".
