• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (su sach)) ly lang xa hoi. hieu va cam ((xuc van) OR (duc van)) dich doc cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (su sach)) ly lang xa hoi. hieu va cam ((xuc van) OR (duc van)) dich doc cua te".
