java - 使用 Solrj 在 Solr 中获取所有结果

Question

我想用 solrj 获得所有结果，我向 Solr 添加了 10 个文档，我没有得到任何异常，但是如果我向 Solr 添加了超过 10 个文档Solr我遇到异常。我在 http://localhost:8983/solr/browse 中搜索，我为此得到了这个异常(exception) 第一页有10个文件，第11个文件到第二页。我怎样才能得到所有结果？

String qry="*:*";
                CommonsHttpSolrServer server = new CommonsHttpSolrServer("http://localhost:8983/solr");
      QueryResponse rsp=server.query(new SolrQuery(qry));
      SolrDocumentList docs=rsp.getResults();  
                        for(int i=0;i<docs.getNumFound();i++){

                            System.out.println(docs.get(i));                    
    }

    Integer start = 0;

    query.setStart(start);
    QueryResponse response = server.query(query);
    SolrDocumentList rs = response.getResults();
    long numFound = rs.getNumFound();
    int current = 0;
    while (current < numFound) {

        ListIterator<SolrDocument> iter = rs.listIterator();
        while (iter.hasNext()) {
            current++;

            System.out.println("************************************************************** " + current + "   " + numFound);
            SolrDocument doc = iter.next();
            Map<String, Collection<Object>> values = doc.getFieldValuesMap();

            Iterator<String> names = doc.getFieldNames().iterator();
            while (names.hasNext()) {
                String name = names.next();
                System.out.print(name);
                System.out.print(" = ");

                Collection<Object> vals = values.get(name);
                Iterator<Object> valsIter = vals.iterator();
                while (valsIter.hasNext()) {
                    Object obj = valsIter.next();
                    System.out.println(obj.toString());
                }
            }
        }
        query.setStart(current);
        response = server.query(query);
        rs = response.getResults();
         numFound = rs.getNumFound();


    }
