The DumpXXX() methods were always documented as internal and unsupported. However, now they are being removed from the public top-level API. They are still available on the internal IndexReader, which can be accessed using the Advanced() method. The DocCount() and DumpXXX() methods on the internal index have moved to the internal index reader, since they logically operate on a snapshot of an index.
