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