ElasticSearch-格式错误的查询（RoR）
我正在尝试使用elasticsearch和ruby-on-
rails建立一个现有项目。我可以启动并运行该项目，但是elasticsearch查询为我返回了各种错误消息，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}这显然使我相信这与我的设置有关。我已经安装了它们的相同版本（2.4），但是即使项目附带了setup命令，也是如此：
rake environment elasticsearch:import:all DIR=app/models FORCE=y给我超时错误。我已经检查并且服务正在运行。如果我在此方面呆了2天，将对我的设置有什么问题的任何帮助将不胜感激。
提前致谢。
编辑：我不认为问题出在查询本身，因为它对我的同事有效，但如下所示：

回答：
问题在于聚合之一，即：
:filter => { :and => [...] }
…这使我得出的结论是，您实际上可能在计算机上运行的是Elasticsearch 5而不是2.4，因为在第5版中删除了该语法，而支持：
:filter => { :bool => { :must: [...] } }
使用curl localhost:9200（或您的应用连接到的实际主机/端口）验证elasticsearch版本。
