• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang ha hoi. hieu ((ve cham) OR (tu cham)) hoc va ((tinh vi) OR (trinh vi)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang ha hoi. hieu ((ve cham) or (tu cham)) hoc va ((tinh vi) OR (trinh vi)) cuu tre".
