• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach tu)) nang ma hoa. hieu ((van pham) OR (san pham)) duc va hanh vai cua tuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach tu)) nang ma hoa. hieu ((van pham) or (san pham)) duc va hanh vai cua tuc".
