jena-text with Lucene requires Solr?
Hello!
trying to use jena-text with Lucene here. But it says
ClassNotFoundException: org.apache.solr.client.solrj.SolrServer because it
tries to load that in TextAssembler.init().
Is there a way to tell it that I don't even want to use Solr? Thanks!
P.S. using Jena 2.10.2 with jean-text from:
https://repository.apache.org/content/repositories/snapshots/org/apache/jena/jena-text/1.0.0-SNAPSHOT/jena-text-1.0.0-20130626.075943-23.jar

Try 'Gurke*'

Thanks! Built with maven now and the dependencies are resolved.
I'm trying to get the text-query code to run from here:
http://jena.apache.org/documentation/query/text-query.html#configuration-by-code
Am I supposed to leave the strings "uri" and "text" as is?
EntityDefinition entDef = new EntityDefinition("uri", "text", RDFS.label) ;
The query simply returns an empty result.
The test data are the two triples:
<http://de.dbpedia.org/resource/Gurkenkraut> <
http://www.w3.org/2000/01/rdf-schema#label> "Gurkenkraut".
<http://de.dbpedia.org/resource/Sauregurkenzeit> <
http://www.w3.org/2000/01/rdf-schema#label> "blablu".
and the query:
SELECT *
{ ?s text:query (rdfs:label 'Gurke' 10) ;
rdfs:label ?label
}
Thanks!

That's the SolrJ, the clients-side interface - not the whole of Solr.
As the POM says:
<dependency>
<artifactId>solr-solrj</artifactId>
<groupId>org.apache.solr</groupId>
<version>${ver.solr}</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
</exclusion>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-jdk14</artifactId>
</exclusion>
</exclusions>
</dependency>
Anything else from solr is scoped to "test" (use of embedded solr for
testing).
