• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky dang cay phoi. hieu viec cac ((luc gia) OR (luoc gia)) thanh gia ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky dang cay phoi. hieu viec cac ((luc gia) OR (luoc gia)) thanh gia ((cua tre) or (cua te))*".
