• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((dang xa) OR (dang xay)) hoi. hieu ve cam lo gia ((thanh vi) OR (thanh ve)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((dang xa) or (dang xay)) hoi. hieu ve cam lo gia ((thanh vi) OR (thanh ve)) cua te".
