Run multiple Fleet searches
- POST also GET /{index}/_fleet/_fleet_msearch
- POST also GET /_fleet/_fleet_msearch
Run several Fleet searches with a single API request.
The API follows the same structure as the multi search API.
However, similar to the Fleet search API, it supports the wait_for_checkpoints parameter.
Required authorization
- Index privileges read
Authentication
Authorization: <value>Elasticsearch APIs support key-based authentication. You must create an API key and use the encoded value in the request header. For example:
curl -X GET "${ES_URL}/_cat/indices?v=true" \
-H "Authorization: ApiKey ${API_KEY}"
To get API keys, use the /_security/api_key APIs.
Authorization: Basic <credentials>Authorization: Bearer <token>Elasticsearch APIs support the use of bearer tokens in the Authorization HTTP header to authenticate with the API.
For examples, refer to Token-based authentication services
Query parameters
-
allow_no_indicesboolean -
A setting that does two separate checks on the index expression. If
false, the request returns an error (1) if any wildcard expression (including_alland*) resolves to zero matching indices or (2) if the complete set of resolved indices, aliases or data streams is empty after all expressions are evaluated. Iftrue, index expressions that resolve to no indices are allowed and the request returns an empty result. -
ccs_minimize_roundtripsboolean · default: true -
If true, network roundtrips between the coordinating node and remote clusters are minimized for cross-cluster search requests.
