Hi!
I'm using ELK via Elasticsearch-PHP. I want to use "explain" in certain circumstances. When I write "explain" or "_explain" before or within "body" the result contains explanation in some cases, but it always returns with exceptions like this:
Elasticsearch\Common\Exceptions\UnexpectedValueException - explain is not a valid parameter. Allowed parameters are allow_no_indices, analyze_wildcard, analyzer, default_operator, df, error_trace, expand_wildcards, filter_path, human, ignore_throttled, ignore_unavailable, lenient, min_score, opaqueId, preference, pretty, q, routing, source, terminate_after

Is it possible and how to get what I want?
Thanks in advance.
