• Performing a fuzzy search may retrieve terms with similar spellings: so sac ky dang xa hoi. ((((hieu ven) OR (hieu ve))) or (hieu hien)) dam tu vat dung co cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sac ky dang xa hoi. ((((hieu ven) OR (hieu ve))) OR (hieu hien)) dam tu vat dung co cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sac ky dang xa hoi. ((((hieu ven) OR (hieu ve))) or (hieu hien)) dam tu vat dung co cua tre*".
