• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) thu dang ha hoi. hieu ve cam ((xuc va) OR (luc va)) thanh vien cua cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) thu dang ha hoi. hieu ve cam ((xuc va) or (luc va)) thanh vien cua cu".
