• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (van ky)) sang lap hai. ((hieu ve) OR (hieu va)) cam xuc ban thanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) OR (van ky)) sang lap hai. ((hieu ve) or (hieu va)) cam xuc ban thanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) OR (van ky)) sang lap hai. ((hieu ve) or (hieu va)) cam xuc ban thanh vi cua te*.
