• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) or (vu bach)) ky tang van hoi. hieu van cam xuc va hanh vai ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) ky tang van hoi. hieu van cam xuc va hanh vai ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (vu bach)) ky tang van hoi. hieu van cam xuc va hanh vai ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (vu bach)) ky tang van hoi. hieu van cam xuc va hanh vai ((cua triet) OR (su triet))*.
