There is no hidden meta information. It's all in a standard Lucene index. Hibernate Search
requires certain fields to be there in order to work, but if you are just using the index from Solr
that's not an issue. 

Creating a solr index can be everything from simple to quite a lot of work. Obviously you could 
just look at an index the containing fields and create the schema. For a more generic solution
you would need the meta information about the indexed field. I don't think that Search exposes 
all meta information in a easy to consume way (yet). This is related to https://hibernate.onjira.com/browse/HSEARCH-436
There wold be obviously much more code to write if you go down this path, but with a much
bigger benefit for Search as well :-)
