When using GraphDB's Lucene connector, how can I access Lucene directly instead of going through SPARQL?

Question

I have been playing with GraphDB's Lucene connector as a way to perform full-text search over a large amount of data, via SPARQL queries. I got the example working.1 Is there another way to read/write Lucene's data, other than going through SPARQL? For lots of large documents, I am concerned that it may be inefficient to load them all through SPARQL, rather than doing some kind of bulk load directly into Lucene.

Is there a way to access Lucene more directly, instead of going through SPARQL?

You have two options:

Switch to GraphDB SOLR or Elasticsearch Connectors - both services expose server APIs accessible by other clients. Unfortunately, this feature is available only in GraphDB Enterprise Edition.
Implement your Lucene server, which works on the same machine running as GraphDB and shares in read-only mode the Lucene index managed by GraphDB.

how do you switch to the GraphDB SOLR connector? In my workbench at Setup/Connectors, I only see the Lucene connector and the option of "New Lucene connector" .

SOLR and ElasticSearch Connectors are available only in GraphDB EE, but not in GraphDB SE or Free
