The text indexed are in the Lucene files.
As per my answer to Harkishan Singh
http://answers.semanticweb.com//questions/26764/indexing-triples-with-larq
(exactly the same question text)
LARQ has been superceded by the jena-text module.
If you have an in-memory RDF graph, use in-memory Lucene and index every
run. Otherwise, use a persistent graph and persistent Lucene, and load
once.
