• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y dang) OR (ky dang)) xay hoi. hieu ve cam xuc ban ((anh hai) OR (lanh hai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y dang) OR (ky dang)) xay hoi. hieu ve cam xuc ban ((anh hai) or (lanh hai)) cua tre".
