Question

我尝试使用elasticsearch和ruby-on-rails设置现有项目。我可以启动并运行该项目，但是弹性搜索查询会为我和我的同事返回各种错误消息：

[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。我安装了它们的相同版本（2.4），但是即使是随项目提供的安装命令：

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

给我一个超时错误。我已经检查过并且服务正在运行。关于我的设置可能出现什么问题的任何帮助都将非常感激，因为我已经死了2天。

提前致谢。

编辑：我不认为问题出在查询本身，因为这适用于我的同事但是如下：

Answer 1

问题在于其中一个聚合，即：

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

...这让我得出结论，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（或您的应用所连接的实际主机/端口）验证elasticsearch版本。
