• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ty nang cao hoi. hieu vu cham lo ((va hanh) OR (va danh)) dai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ty nang cao hoi. hieu vu cham lo ((va hanh) or (va danh)) dai ((cua tre) OR (cua te))".
