David Smiley commented on SOLR-139:
-----------------------------------

Yonik; I don't see your patch.  Will this support the ability to replace a text field that is indexed?  If so, what is the essence of the implementation?  The most common use-case I need for my employer involves essentially a complete re-indexing of all docs but only for a few particular fields. I tend to think, at least for my use-case, that it is within reach if I had enough time to work on it.  The implementation concept I have involves building parallel segments with aligned docids.  Segment merging would clean out older versions of a field.

> It would be nice to be able to update some fields on a document without having to insert the entire document.
> Given the way lucene is structured, (for now) one can only modify stored fields.
> While we are at it, we can support incrementing an existing value - I think this only makes sense for numbers.
