• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky dang ha hoi. hieu ((va tham) OR (((van tham) OR (van thanh)))) duc va dan thi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky dang ha hoi. hieu ((va tham) or (((van tham) OR (van thanh)))) duc va dan thi cuu tre*".
