• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) nang ma hoa. hieu van chat ((huu va) OR (cuu va)) dan cho cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sach y)) nang ma hoa. hieu van chat ((huu va) OR (cuu va)) dan cho cau treo".
