• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach ty)) tang xa hoi. hieu vien bach xuc gia ((thanh va) OR (thanh ha)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach ty)) tang xa hoi. hieu vien bach xuc gia ((thanh va) or (thanh ha)) cuu tre".
