I might be misunderstanding the purpose of this pull request.  But, I was wondering why the search & browse indexes are still enabled by default?  Is it because the JSPUI doesn't support Discovery by default yet?

I guess my point here is that it seems like we are still generating multiple search/browse indexes in DSpace, which it'd be nice to get away from.  Ideally, if we can get both the XMLUI & JSPUI supported, we could *just* create the Discovery index, and avoid indexing in Lucene (for search) and the database (for browse) by default anymore.

If I'm misunderstanding, please let me know.
