ES分页查询，想偷懒，数据超过一万多一些可以设置一下max_result_window
Map<String,String> params = Collections.singleMap("pretty","true");
String json = "{"
+"\"index\":{"
+"\"max_result_window\":30000"
+"}"
+"}"
HttpEmpty entity = new NStringEntity(json,ContentType.APPLICATION_JSON);
response = restClient.performRequest("PUT","/_index/_settings",params,entity);
但还是建议使用scrollId 查询。
java 传json 设置 ES max_result_window
