• If you are trying to use Boolean operators, they must be ALL CAPS: so canh may nang x hoi. hieu ve phan thuc ((day hanh) OR (day nhanh)) ((vai cua) OR (lai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so canh may nang x hoi. hieu ve phan thuc ((day hanh) OR (day nhanh)) ((vai cua) or (lai cua)) tre*".
