Request search

Request a search to the search engine. The index parameter should contain the desired index and the query parameter should contain the desired query in the Elasticsearch query format. By default, the results will be in JSON format. If you wish CSV output instead, supply a list of field names in the columns parameter. Please note that, as a limitation of Elasticsearch, array fields cannot be placed in CSV output in their entirety; only the first value will be.

This endpoint spawns a background operation and returns a tracking ID that should be used to poll operation status to determine when the results become available. Refer to the Asynchronous Operations section for more information.
