Clear cache

[ngouy]

Hello

Is there a provided tool / func / rake whatever to perform this kind of operation :
https://www.elastic.co/guide/en/elasticsearch/reference/current//indices-clearcache.html
(clear search cache for exemple)

I search for it without success.

If yes I will be delighted to know what is it and maybe if it's ok for you I would submit a PR to update some guides / readme(s)

This need coms from a issue in my specs.
When testing search + order by many stuff (including SCORE)
depending on what tests ran before, scores are not always the same for the same query, so are results order

Right now we don't have this operation implemented and you could invoke this directly on elasticsearch-api client with this:
https://www.rubydoc.info/gems/elasticsearch-api/Elasticsearch/API/Indices/Actions#clear_cache-instance_method

It would be nice to add this feature, surely a PR would be welcome
