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