Re: Lucene Index

[Rob Vesse]

What these lines are doing is creating a blank index, in particular the last 
line simply associates a pre-existing index with a dataset i.e. It doesn’t 
actually cause indexing to happen, typically you would first build a persistent 
Lucene index using the command line tool

http://jena.apache.org/documentation/query/text-query.html#building-a-text-index

 if you want to explicitly built the index from code your best bet is to refer 
to the code for the commandline tool:
