django - 无法使用:TransportErrorr(400， 'parsing_exception')查询Elasticsearch

Question

我一直在尝试让Elasticsearch在Django应用程序中工作。这是一个问题，因为显然涉及兼容性问题。我遵循了建议，但是在实际执行搜索时仍然出现错误。

这是我所拥有的

Django==2.1.7
Django-Haystack==2.5.1
Elasticsearch(django)==1.7.0
Elasticsearch(Linux app)==5.0.1

还有 DjangoCMS==3.7和 aldryn-search=1.0.1，但我不确定它们之间的相关性。

这是我通过基本文本表单提交搜索查询时遇到的错误。

GET /videos/modelresult/_search?_source=true [status:400 request:0.001s]
Failed to query Elasticsearch using '(video)': TransportError(400, 'parsing_exception')

raise HTTP_EXCEPTIONS.get(status_code, TransportError)(status_code, error_message, additional_info)
elasticsearch.exceptions.RequestError: TransportError(400, 'parsing_exception')

有人可以告诉我这是兼容性问题还是其他问题？我该如何解决？

看来对我的设置有用的组合如下。我相信关键是要大大降低Elasticsearch的等级。

Elasticsearch=1.7.6 (with Java 8)
Django==2.1.7
Django-Haystack==2.8.1
elasticsearch==1.7.0

以下两个项目可能相关也可能不相关。我没有改变他们。

DjangoCMS==3.7.0
aldryn-search==1.0.1
