Subject [Lucene.Net] [jira] [Commented] (LUCENENET-417) implement streams as field values
Date Thu, 26 May 2011 00:35:47 GMT

    [ https://issues.apache.org/jira/browse/LUCENENET-417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13039452#comment-13039452
] 

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).

> 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.
