• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu cac)) ky sang ma hoi. hieu vu kham luu ((van anh) OR (van thanh)) via cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) or (tu cac)) ky sang ma hoi. hieu vu kham luu ((van anh) OR (van thanh)) via cua tre*".
