Thank you for fast reply, I add the query in the code but still not working:
////////////////////////////////////////////////////////////
import java.util.List;

public class App3 {
public static void main(String[] args) throws Exception {
String urlString = "http://localhost:8983/solr/techproducts";;
SolrClient solr = new HttpSolrClient.Builder(urlString).build();
SolrQuery query = new SolrQuery();
query.setQuery("*:*");
query.setTerms(true);
query.addTermsField("name");
SolrRequest<QueryResponse> req = new QueryRequest(query);
QueryResponse rsp = req.process(solr);
System.out.println(rsp);
System.out.println("numFound: " + rsp.getResults().getNumFound());
TermsResponse termResp =rsp.getTermsResponse();
List<TermsResponse.Term> terms = termResp.getTerms("name");
System.out.print("size="+ terms.size());
}
}
