• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang o hoi. hieu van cam xuc va ((dinh dinh) OR (dinh kinh)) ((cau treo) or (cau theo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang o hoi. hieu van cam xuc va ((dinh dinh) OR (dinh kinh)) ((cau treo) OR (cau theo)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang o hoi. hieu van cam xuc va ((dinh dinh) OR (dinh kinh)) ((cau treo) or (cau theo))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang o hoi. hieu van cam xuc va ((dinh dinh) OR (dinh kinh)) ((cau treo) or (cau theo))*.
