Solr is meant to store the indexable parts of documents. You can of
course store anything, but there's no versioning, no locks, etc., the
focus is really on indexing, not storage.

Yes, when it comes to indexing and searching.

Jackrabbit and Solr both base their indexing stuff on Lucene, and add
some features on top of it.

That set of additional features could probably be (at least partially)
factored out and moved to Lucene as extensions that would be used by
both projects, but there are also significant differences due to the
way indexes are used by Solr (as a core functionality) and Jackrabbit
(as one module that's more tightly integrated with the storage
features). So that's probably not as trivial as it might seem.
