• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty ((hang x) OR (hoang xa)) hoi. ((hieu va) OR (lieu va)) cac luc gia thanh hoi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty ((hang x) or (hoang xa)) hoi. ((hieu va) OR (lieu va)) cac luc gia thanh hoi cua te*".
