Mike Mattozzi updated SOLR-1752:
--------------------------------

    Attachment: SOLR-1752.patch

I ran into this problem today and was surprised it hadn't been fixed. I've attached a patch to UpdateRequest that maintains an ordered list that can be a mix of SolrInputDocuments to add, ids to delete, and delete queries. 

There's a few places where my patch iterates over documents instead of doing an addAll so there may be some inefficiencies. It seems like these would be outweighed by the ability to group up update operations, but I could always optimize more.
