> Adding binary values to a field is an expensive operation, as the whole binary data must
be loaded into memory and then written to the index.  Adding the ability to use a stream instead
of a byte array could not only speed up the indexing process, but reducing the memory footprint
as well.
> Java lucene has the ability to use a TextReader the both analyze and store text in the
index.  .NET lacks the ability to store the data in the index, due to the fact that .net TextReaders
cannot seek or reset the position of the stream.  This should be a feature added into Lucene.NET
as well.  My thoughts are to add another Field constructor, that is Field(string name, System.IO.Stream
stream, System.Text.Encoding encoding), that will allow the text to be analyzed and stored
into the index.
> Comments about this approach are greatly appreciated.
