Recently someone mentioned that it would be possible to have a

existing document' feature rather than just dropping and adding

There is such a patch: https://issues.apache.org/jira/browse/SOLR-139
I'm experimenting with it right now and it works well for my cases.
However, it is still under the covers a delete/add and....
One use case is that we would like to use the index as our one
database for
documents, and if we delete a document we want it to stay deleted.
Thus we
would mark it deleted and check for its existence. Another use case
is that
we are re-adding the same document a few times a day, and the
commit times
are ballooning.
