Ryan McKinley updated SOLR-1566:
--------------------------------
Attachment: SOLR-1566-rm.patch
attaching some stuff that really does not work, but at least sketches a
direction till it hit the 'how do we actually write the fields' road block...
posting here just for reference.
This takes the approach of adding an 'augmenter' calss:
{code:java}
public abstract class DocAugmenter
{
/**
* Call this before you start writing out fields
* @param rsp
* @param req
*
* @return true if it has any fields to augment
*/
public abstract boolean setup(SolrQueryRequest req);
/**
* Make sure 'setup' has been called first!
*/
public abstract void augment( int docId, Document doc );
}
{code}
the 'setup' call give the augmeter a chance to bulk load all the values if that
is what it wants to do. perhaps we would want a shutdown also

> it cumbersome to add computed fields/metadata .
