Ryan McKinley commented on SOLR-139:
------------------------------------

> That wouldn't work for multi-valued fields though, right?

'REMOVE' on a mult-valued field would clear the old fields before adding the new ones.  It
is essentially the same as OVERWRITE, but you may or may not pass in a new value on top of
the old one.

> If we keep this option, perhaps we should find a better name... 

how about 'IGNORE' or 'CLEAR'  It is awkward because it refers to what was in in the document
before, not what you are passing in.

The more i think about it, I think we should drop the 'REMOVE' option.  You can get the same
effect using 'OVERWRITE' and passing in a null value.

> 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.
