• If you are trying to use Boolean operators, they must be ALL CAPS: thu cach tu nang mai hoi. hieu ((va cham) OR (ve chat)) duc va thanh dai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu cach tu nang mai hoi. hieu ((va cham) or (ve chat)) duc va thanh dai ((cua tre) OR (cua te))".
