• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty lang xa hoi. hieu ve cam tuc va ((thanh hai) OR (thanh hoa)) ((cuu tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty lang xa hoi. hieu ve cam tuc va ((thanh hai) OR (thanh hoa)) ((cuu tre) or (cua triet))".
