Lucene Index

[Dimov, Stefan]

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?

S.
