Clarification – the prefix p is defined like this:
so the triples are:
@base <http://ao.com/> .
@prefix p: <p/> .
p:p1 <name> "abc fdjfh jlkgjdf"
.
p:p2 <name> "fsdkfj abc ffdsfs"
.

Hello,
I’m trying to create Lucene index (from Java) in my app
The test triples I have are:
@base <http://ao.com/> .
p:p1 <name> "abc fdjfh jlkgjdf"
.
p:p2 <name> "fsdkfj abc ffdsfs"
.
And my code to create the index is:
Dataset ds = loadData();
…
Resource res = ResourceFactory.createProperty("http://ao.com/name/";);
EntityDefinition entDef = new EntityDefinition("uri", "text", res) ;
Directory dir = new RAMDirectory();
Dataset indexDataset = TextDatasetFactory.createLucene(ds, dir, entDef,
null);
…
FusekiEmbeddedServer server = FusekiEmbeddedServer.create().add("/ds",
indexDataset).build() ;
server.start() ;
The server is starting and I can query the loaded data with regular SPARQL
queries, but when I try to use the index (assuming I’ve created it correctly):
PREFIX text: <http://jena.apache.org/text#>
SELECT ?s
{
?s text:query 'abc' ;
}
I get empty results:
{
"head": {
"vars": [ "s" ]
} ,
"results": {
"bindings": []
}
}
What am I doing wrong?
