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