• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (so sanh)) ty nang xa hoi. hieu hien ((bach nuoc) OR (bach tuoc)) va danh vi cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (so sanh)) ty nang xa hoi. hieu hien ((bach nuoc) OR (bach tuoc)) va danh vi cua tu~".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (so sanh)) ty nang xa hoi. hieu hien ((bach nuoc) OR (bach tuoc)) va danh vi cua tu*.
