• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (hoc anh)) ky nang xa hoi. hieu ((van cham) OR (va cham)) tuc va thanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (hoc anh)) ky nang xa hoi. hieu ((van cham) OR (va cham)) tuc va thanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (hoc anh)) ky nang xa hoi. hieu ((van cham) OR (va cham)) tuc va thanh vi cua triet*.
