• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien danh) OR (hieu manh)) - thanh tung ((van thang) OR (van thanh)) cong vang quang cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien danh) or (hieu manh)) - thanh tung ((van thang) OR (van thanh)) cong vang quang cao*".
