• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky ((nang cao) OR (dang van)) hoi. hieu van nam xuc ((van anh) OR (tuan anh)) de cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky ((nang cao) or (dang van)) hoi. hieu van nam xuc ((van anh) OR (tuan anh)) de cua triet*".
