        3. SolrQuery solrQuery = new SolrQuery(query);
        4. QueryResponse queryResponse = client.query(solrQuery);
        5. int start = 0;
        6. long totalCount = queryResponse.getResults().getNumFound();
        7. while (start < totalCount) {
        8. ListIterator<SolrDocument> result = queryResponse.getResults().listIterator();
        10. while (result.hasNext()) {
        11.   start += 1;
        12.   SolrDocument doc = result.next();
        13.   System.out.println(doc.get("id"));
        14. }
        15. solrQuery.setStart(start);
        16. queryResponse = client.query(solrQuery);
        17. totalCount = queryResponse.getResults().getNumFound();
        18. }
