• Performing a fuzzy search may retrieve terms with similar spellings: su cac tu nano 1 ho. hieu ((ve cham) OR (va cham)) xuc va hanh vi ((cua triet) or (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cac tu nano 1 ho. hieu ((ve cham) OR (va cham)) xuc va hanh vi ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac tu nano 1 ho. hieu ((ve cham) OR (va cham)) xuc va hanh vi ((cua triet) or (cua viet))".
• Adding a wildcard symbol may retrieve word variants: su cac tu nano 1 ho. hieu ((ve cham) OR (va cham)) xuc va hanh vi ((cua triet) or (cua viet))*.
