• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly nang xa hoi. hieu van cam xuc ((va danh) OR (va hanh)) ((di cua) OR (dai cua)) viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly nang xa hoi. hieu van cam xuc ((va danh) OR (va hanh)) ((di cua) or (dai cua)) viet".
• Adding a wildcard symbol may retrieve word variants: te sach ly nang xa hoi. hieu van cam xuc ((va danh) OR (va hanh)) ((di cua) or (dai cua)) viet*.
