• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach tu)) lang xa hoi. hieu ve cam cua ban ((danh vi) OR (dinh vi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach tu)) lang xa hoi. hieu ve cam cua ban ((danh vi) or (dinh vi)) cua tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ty) OR (sach tu)) lang xa hoi. hieu ve cam cua ban ((danh vi) or (dinh vi)) cua tre*.
