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