• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky ((sang ma) OR (sang tao)) hoi. hieu van cac lo van anh ((via cua) OR (gia cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky ((sang ma) OR (sang tao)) hoi. hieu van cac lo van anh ((via cua) or (gia cua)) te*".
