• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - thanh ((tung qua) OR (trung quan)) ((dung hang) OR (dung dang)) luan toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - thanh ((tung qua) OR (trung quan)) ((dung hang) or (dung dang)) luan toan cao*".
