Hi
I've checked lots of things for 2 days.
I have this scenario in semantic_forms:
- on fresh TDB and LUCENE directories
- load rdfs: (the ontology)
- create instance of class bli:bli (sic !)
- enter rdfs:comment bli
- search bli => NOTHING !!! :(
I wrote a self-contained test with no semantic_forms nor Banana
dependency, that reproduces the same scenario by theAPI:
https://github.com/jmvanel/semantic_forms/blob/master/scala/forms/src/main/scala/deductions/runtime/jena/lucene/TestTextIndex2.scala
But it succeds !!!
So I wrote another test that runs on the TDB that was prepared in the above
scenario in semantic_forms:
https://github.com/jmvanel/semantic_forms/blob/master/scala/forms/src/main/scala/deductions/runtime/jena/lucene/QueryTextIndex.scala
The indexing seems normal on Lucene + Jena side, but NOT the SPARQL search
with text:query .
runMain deductions.runtime.jena.lucene.QueryTextIndex bli TDB
...

The URI in Lucene dump is correct. I'm surprised that field "lang" appears
2 times, and "graph" not at all .
I've looked in the Jena code, and the member fields in EntityDefinition
https://github.com/apache/jena/blob/master/jena-text/src/main/java/org/apache/jena/query/text/EntityDefinition.java#L39
looks as if it is not always updated.
fields is initialized once from fieldToPredicate, and I'm not sure that
fieldToPredicate is initialized before;
moreover it is modified by method
void set(String field, Node predicate)
https://github.com/apache/jena/blob/master/jena-text/src/main/java/org/apache/jena/query/text/EntityDefinition.java#L126
