• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) xu ((lang xa) OR (lang ha)) hoi. lieu va co thuc va thanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (toc sach)) xu ((lang xa) OR (lang ha)) hoi. lieu va co thuc va thanh vai cua tre".
