> While working on SOLR-5944, I needed a way to know whether applying an update to a DV is possible (i.e. the DV exists or not), while deciding upon whether or not to apply the update as an in-place update or a regular full document update. This information is present at the IndexWriter in a FieldInfos instance, and can be exposed.
