The self-contained test with no semantic_forms nor Banana dependency, that
reproduces the scenario by the API:
https://github.com/jmvanel/semantic_forms/blob/master/
scala/forms/src/main/scala/deductions/runtime/jena/
lucene/TestTextIndex2.scala
now FAILS!
Jena problem:
when adding first a named graph with no relevant data,
and second the named graph with relevant data,
the SPARQL query with text:query FAILS.
It looks as if only the first named graph is used in SPARQL processing.
It is a regression after the migration to recent Lucene version.
It looks as if nobody tested Jena + Lucene with several named graphs ...
