• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dang xay hoi. nhieu viec cam xuc va ((tinh de) OR (sinh de)) ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky dang xay hoi. nhieu viec cam xuc va ((tinh de) OR (sinh de)) ((cua tre) or (cua te))*".
