• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty xang ma hoi. hieu ((ve cac) OR (va cam)) tuc ((van anh) OR (tuan anh)) vi hoa viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty xang ma hoi. hieu ((ve cac) or (va cam)) tuc ((van anh) OR (tuan anh)) vi hoa viet".
