• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu khach)) ky ((nang van) OR (lang van)) hoi. hieu van nam xuc va hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu khach)) ky ((nang van) or (lang van)) hoi. hieu van nam xuc va hanh vi cua triet*".
