使用多个索引时，elasticsearch扫描/滚动不起作用

Question

我的扫描/滚动工作正常，有一个索引：

http://localhost:9200/2014-07-10/picture/_search?search_type=scan&scroll=1m

所以，现在我正在尝试使用多个索引做同样的事情。

http://localhost:9200/2014-07-*/picture/_search?search_type=scan&scroll=1m

这将返回一个巨大的scroll_id：

因此，当我尝试使用此scroll_id滚动时，它会返回CONN_REFUSED并刷新服务器。

这是一个问题吗？也许性能问题？或者无法扫描多个索引？
