ElasticSearch - 格式错误的查询（RoR）

Question

我正在尝试使用elasticsearch和ruby-on-rails建立现有项目。 我可以启动并运行该项目，但elasticsearch查询会为我返回各种错误消息，而我的同事都没有：

[400] {"error":{"root_cause":[{"type":"parsing_exception","reason":"[and] query malformed, no start_object after query name","line":1,"col":896}],"type":"parsing_exception","reason":"[and] query malformed, no start_object after query name","line":1,"col":896},"status":400}

这显然让我相信它与我的设置有关。 我已经安装了它们的相同版本（2.4），但是即使是随项目提供的setup命令：

rake environment elasticsearch:import:all DIR=app/models FORCE=y

给我一个超时错误。 我已经检查过，服务正在运行。 任何关于我的设置可能出错的帮助都会非常感激，因为我已经死了2天了。

提前致谢。

编辑：我认为问题不在于查询本身，因为这适用于我的同事，但它如下：

Answer 1

问题在于其中一个聚合，即：

:filter => { :and => [...] }

...这导致我得出结论，你实际上可能在你的机器上运行elasticsearch 5而不是2.4，因为这个语法在版本5中被删除而支持：

:filter => { :bool => { :must: [...] } }

使用curl localhost:9200 （或您的应用程序连接的实际主机/端口）验证elasticsearch版本。
