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