solrj 怎么样把查询数据返回到前端

Question

rt.我想的是把查询结果转化成json，返回到前台。

public JSON search(String keyWords) throws SolrServerException {
		HttpSolrServer server = new  HttpSolrServer("http://localhost:8080/solr-4.2.1/collection1/");
		ModifiableSolrParams params = new ModifiableSolrParams();
	    params.set("qt", "/select");
	    params.set("q","desc:"+keyWords);
        params.set("start", 0);
        params.set("rows", 5);
	    params.set("wt","json");
	    QueryResponse response = server.query(params);
	    SolrDocumentList docs = response.getResults();
}

Answer 1

docs.toString()
