Jack Krupansky commented on SOLR-139:
-------------------------------------
I just tried it and the feature does work as advertised. If there is a bug,
that should be filed as a separate issue. If there is a question or difficulty
using the feature, that should be pursued on the Solr user list.
For reference, I took a fresh, stock copy of the Solr 4.0 example, no changes
to schema or config, and added one document:
{code}
curl 'localhost:8983/solr/update?commit=true' -H
'Content-type:application/json' -d '
[{"id":"id-123","title":"My original Title", "content": "Initial content"}]'
{code}
I queried it and it looked fine.
I then modified only the title field:
{code}
curl 'localhost:8983/solr/update?commit=true' -H
'Content-type:application/json' -d '
[{"id":"id-123","title":{"set":"My new title"}}]'
{code}
I tried the XML equivalents and that worked fine as well, with the original
content field preserved.

> 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.
