• Performing a fuzzy search may retrieve terms with similar spellings: tu cac tu ((nang xa) or (nang ma)) hoi. ((hieu ve) OR (hieu va)) cam duc va thanh lai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac tu ((nang xa) OR (nang ma)) hoi. ((hieu ve) OR (hieu va)) cam duc va thanh lai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac tu ((nang xa) or (nang ma)) hoi. ((hieu ve) OR (hieu va)) cam duc va thanh lai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu cac tu ((nang xa) or (nang ma)) hoi. ((hieu ve) OR (hieu va)) cam duc va thanh lai cua tre*.
