Subject [Lucene.Net] [jira] [Updated] (LUCENENET-417) implement streams as field values
Date Tue, 14 Jun 2011 18:28:47 GMT

     [ https://issues.apache.org/jira/browse/LUCENENET-417?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Christopher Currens updated LUCENENET-417:
------------------------------------------

    Attachment: StreamValues.patch

Adding another patch that adds Streaming capabilities for both Binary and String values.

String values are still input as streams, however, must include the encoding to be used as
string, otherwise it will be treated as binary.

> 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.
