• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty ((hang ca) OR (hang va)) hoi. hieu ((ve tao) OR (ve tac)) duoc va danh va cua cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty ((hang ca) OR (hang va)) hoi. hieu ((ve tao) or (ve tac)) duoc va danh va cua cu".
