Troy Howard commented on LUCENENET-417:
---------------------------------------
Stream.CanSeek should be enough. We can throw a runtime exception if someone is
trying to store an indexed field with a Stream value that has a false CanSeek.
This will basically be the same experience it is now (runtime exception if you
pass a TextReader value type for an indexed field).
> implement streams as field values

> Key: LUCENENET-417
> URL: https://issues.apache.org/jira/browse/LUCENENET-417
> Project: Lucene.Net
> Issue Type: New Feature
> Components: Lucene.Net Core
> Reporter: Christopher Currens
> Attachments: BinaryStream.patch
>
>
> 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.- Lucene.NET lacks the ability to store string data in the
> index via streams. 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.
