• If you are trying to use Boolean operators, they must be ALL CAPS: toc sac ky dang ha hoi. hieu ve cham duc tan thanh vi ((((cua te) OR (cua tu))) OR (cua su))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sac ky dang ha hoi. hieu ve cham duc tan thanh vi ((((cua te) OR (cua tu))) or (cua su))*".
