> Solr's normal behavior is to create an "index" dire in the dataDir if one 
> does not already exist, but if "index" does exist it is used as is, warts and 
> all ... if the index is corrupt in some way, and Solr can't create an 
> IndexWriter or IndexReader that error is propagated up to the user.
> I don't think this should change: Solr shouldn't attempt to do anything 
> special if there is a low level problem with the index, but something that 
> i've seen happen more then a few times is that people unwittingly "rm 
> index/*" when they should "run -r index" and as a result Solr+Lucene gives 
> them an error instead of just giving them an empty index
> when checking if an existing index dir exists, it would probably be worth 
> while to add a little one line sanity test that it contains some files, and 
> log a warning.
