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