• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sac ky) OR (sach ty)) tang lai hoi. hieu ve cham xuc va luan dan ((cua tu) OR (cua su))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sac ky) or (sach ty)) tang lai hoi. hieu ve cham xuc va luan dan ((cua tu) OR (cua su))*".
