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