• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach tu)) nang ma hoa. hieu ve cham ((xuc va) OR (duc va)) hanh tai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach tu)) nang ma hoa. hieu ve cham ((xuc va) or (duc va)) hanh tai cau treo".
