Noble Paul updated SOLR-1566:
-----------------------------
Attachment: SOLR-1566.patch
idea as a patch.
Any component must be able to add fields to the document. There are two ways to
do it. Add the value directly or add a component (DocFieldSource) which will
add the value just in time before the document is written out. The component
can choose to add the values based on the other values or it can add some
metadata to the document
There is a new class SolrDocumentSlice extends DocSlice . The requirement is
that all responsewriters must use SolrDocumentSlice#getSolrDocumentIterator()
to write out documents.
I have not made the necessary changes to the response writers yet. I wish to
get the feedback from others on the approach before going ahead further

> are not in the the stored fields of the document. This makes it cumbersome
> to add computed fields/metadata .
