Open Stack

Hi,

I'm reading the documentation for Searchlight and it's recommending
ElasticSearch 5.x:
https://docs.openstack.org/searchlight/latest/install/elasticsearch.html

I installed and tried to use Elasticsearch 5 and it doesn't work. The
queries sent by Searchlight aren't accepted by Elasticsearch. For
examples:

When listing facets:
TransportError(400, u'parsing_exception', u'[terms] failed to parse
field [size]'): RequestError: TransportError(400,
u'parsing_exception', u'[terms] failed to parse field [size]')

When searching for images:
No registered plugin for type owner: Exception: No registered plugin
for type owner

Is there any work in progress to add support for Elasticsearch 5?
In fact, Elasticsearch 5 is EOL. Are there plans to support later versions?

Thanks
