• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky nang xa hoi. hieu va ((cam tuc) OR (cam xuc)) ((xa trong) OR (ca trong)) doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky nang xa hoi. hieu va ((cam tuc) or (cam xuc)) ((xa trong) OR (ca trong)) doi cua tre".
• Adding a wildcard symbol may retrieve word variants: so sach ky nang xa hoi. hieu va ((cam tuc) or (cam xuc)) ((xa trong) OR (ca trong)) doi cua tre*.
