Search Explain API (beta)edit
The Search Explain API is a beta feature. Beta features are subject to change and are not covered by the support SLA of generally available (GA) features. Elastic plans to promote this feature to GA in a future release.
A Private API key is required to access this endpoint.
Submit a search and receive an Elasticsearch query built by App Search. You can submit the query directly to Elasticsearch to retrieve the search results.
This API can be used with regular engines and meta-engines.
