• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((dan lap) OR (sang tai)) hoi. hieu ve cam ((xuc va) OR (luc va)) hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((dan lap) or (sang tai)) hoi. hieu ve cam ((xuc va) OR (luc va)) hanh vi cua te*".
