That loads the RDF data into the memory model directly, bypassing the
text index. To set the index, you'll need to load somehow with the same
data offline or start an empty server then push the data into it.
BTW1 text:directory "mem"
wil create an in-mmeory Lucense index.)
BTW2 There is an in-memory dataset implementation
:memory_dataset rdf:type ja:MemoryDataset;
ja:data "data.trig";
.

Server startup works fine, and the data from my owl file is loaded
successfully. I can check it by executing:
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX ns:<
http://www.semanticweb.org/rodrigo/ontologies/2020/7/untitled-ontology-7#>
PREFIX owl:<http://www.w3.org/2002/07/owl#NamedIndividual>
PREFIX owls: <http://www.daml.org/services/owl-s/1.2/Service.owl#>
PREFIX text: <http://jena.apache.org/text#>
SELECT ?brand
WHERE {
?brand rdfs:subClassOf ns:mobile-phones .
}
However, I get no result when I execute a text query:
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX ns:<

PREFIX owl:<http://www.w3.org/2002/07/owl#NamedIndividual>
PREFIX owls: <http://www.daml.org/services/owl-s/1.2/Service.owl#>
PREFIX text: <http://jena.apache.org/text#>
SELECT ?s { ?s text:query ('samsung') }
This behavior, according to this thread
<https://jena.markmail.org/thread/grni3o6ch5tfak4j> and JENA-956
<https://issues.apache.org/jira/browse/JENA-956>, has been fixed in 3.0.0,
but I can't get this to work as expected. Am I doing something wrong?
