This the error I get it is the same:
Exception in thread "main" java.lang.NullPointerException
at solr_test.solr.SolrJTermsApplication.main(SolrJTermsApplication.java:30)
I know the object is null but I don't know why it is null??
when I change the query to this:
SolrQuery query = new SolrQuery();
query.setQuery("*:*");
SolrRequest<QueryResponse> req = new QueryRequest(query);
QueryResponse rsp = req.process(solr);
System.out.println("numFound: " +
rsp.getResults().getNumFound());
I get results but the problem I want to get term frequency in the field
"name" how can I do that???
Thank you!
