• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty hang) OR (thi hang)) co hoc. hieu ve cam xuc gia ((thanh vai) OR (thanh tai)) cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty hang) or (thi hang)) co hoc. hieu ve cam xuc gia ((thanh vai) OR (thanh tai)) cau treo".
