• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu khach)) ky nang may hoi. hieu ve cam xuc ((tuan anh) OR (van minh)) va hoc viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu khach)) ky nang may hoi. hieu ve cam xuc ((tuan anh) or (van minh)) va hoc viet*".
