Do I have to set the datasource that my index references?

My data is stored in a database, I want Solr to look up the data in that
database using my existing index. At the moment, I have set the <dataDir>
element in my solrconfig to point at my existing index, and checked the
schema on my existing index using Luke but I can't get any results when
searching in Solr.

My index was created using hibernate-search. 

How I can retrieve my data in Solr, using the existing Lucene index? I think
I need to set the database connection details somewhere, just not sure
where. I have set up a dataImport handler, but I don't want that to
overwrite my exising index.
