David Smiley commented on SOLR-139:
-----------------------------------
I agree Lance. I don't know what the "first design" is that might be bogus
you're talking about... but we definitely *eventually* want to handle
non-stored fields. I have an index that isn't huge and I'm salivating at the
prospects of doing an update. For non-stored fields... it seems that if an
update always over-writes such fields with new data then we should be able to
support that now easily because we don't care what the old data was.
For non-stored fields that need to be retained (Otis & Yoniks concern)... I
wonder what Lucene exposes about the indexed data for a non-stored field. We'd
just want to copy this low-level data over to a new document, basically.

> 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.
