ℹ️ For new users, we recommend using our native Elasticsearch tools, rather than the standalone App Search product. We are actively developing new features and capabilities in the Elastic Stack to help you build powerful search applications.

POST /api/as/v1/engines/<engine_name>/search_explain
Request body
editRequest body is exactly the same as the one in Search API: Request body.
Response body
edit-
query_string -
Query string to be used as part of request to Elasticsearch.
-
query_body -
JSON query to be used as part of request to Elasticsearch.
-
meta -
Object delimiting the results meta data.
-
meta.request_id -
String ID representing the request. Guaranteed to be unique.
Use the ID with the API logs API to search for API requests.
-
meta.warnings -
