• Performing a fuzzy search may retrieve terms with similar spellings: su cach tu nano x ho. hieu van cham xuc ((va hanh) OR (va danh)) vi ((cua triet) or (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cach tu nano x ho. hieu van cham xuc ((va hanh) OR (va danh)) vi ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cach tu nano x ho. hieu van cham xuc ((va hanh) OR (va danh)) vi ((cua triet) or (cua viet))".
• Adding a wildcard symbol may retrieve word variants: su cach tu nano x ho. hieu van cham xuc ((va hanh) OR (va danh)) vi ((cua triet) or (cua viet))*.
