• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh kho tang xa hoi. hieu ((((ve cham) OR (ve chim))) OR (ve chat)) tuc ban nhanh hoa su triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh kho tang xa hoi. hieu ((((ve cham) OR (ve chim))) or (ve chat)) tuc ban nhanh hoa su triet~".
• Adding a wildcard symbol may retrieve word variants: so sanh kho tang xa hoi. hieu ((((ve cham) OR (ve chim))) or (ve chat)) tuc ban nhanh hoa su triet*.
