• If you are trying to use Boolean operators, they must be ALL CAPS: tu can ky dang xa hoi. chieu tu nguon luc ((va hanh) OR (dia danh)) dai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky dang xa hoi. chieu tu nguon luc ((va hanh) or (dia danh)) dai ((cua tre) OR (cua triet))".
