• Performing a fuzzy search may retrieve terms with similar spellings: tu can kho tang ma hoi. ((hieu ve) or (hieu van)) cam duc van ((anh vi) OR (anh va)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu can kho tang ma hoi. ((hieu ve) OR (hieu van)) cam duc van ((anh vi) OR (anh va)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can kho tang ma hoi. ((hieu ve) or (hieu van)) cam duc van ((anh vi) OR (anh va)) cuu tre*".
