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