Failed to query Elasticsearch using : TransportErrorr(400, 'parsing_exception')

I have been trying to get the Elasticsearch to work in a Django application. It has been a problem because of the mess of compatibility considerations this apparently involves. I follow the recommendations, but still get an error when I actually perform a search.

Here is what I have

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

There is also DjangoCMS==3.7 and aldryn-search=1.0.1, but I am not sure how relevant those are.

Here is the error I get when I submit a search query via the basic text form.

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

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

Could someone tell me if this is an issue with compatibility or is there something else going on? How can I fix it?

The combination that appears to have worked for my setup is as follows. I believe the key was to drastically downgrade the Elasticsearch.

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

The two items below may or may not be relevant. I have not changed them.

DjangoCMS==3.7.0
aldryn-search==1.0.1
