• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) uu nang ((ma hoi) OR (dai hoi)). hieu ve cam xuc va lang hai cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) uu nang ((ma hoi) or (dai hoi)). hieu ve cam xuc va lang hai cua tu".
