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