• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach y) OR (sach thieu)) nang xa hoi. hieu van chat xuc va ((danh hai) OR (dang hai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach y) or (sach thieu)) nang xa hoi. hieu van chat xuc va ((danh hai) OR (dang hai)) cua tre".
