• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) ty hang xa hoi. hieu van cam xuc va ((thanh vien) OR (thanh ha)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) ty hang xa hoi. hieu van cam xuc va ((thanh vien) or (thanh ha)) cua tre".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) ty hang xa hoi. hieu van cam xuc va ((thanh vien) or (thanh ha)) cua tre*.
