Flushes one or more data streams or indices

GET /_flush

Query parameters

allow_no_indices boolean

If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices.
expand_wildcards string | array[string]

Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are: all, open, closed, hidden, none.
force boolean

If true, the request forces a flush even if there are no changes to commit to the index.
ignore_unavailable boolean

If false, the request returns an error if it targets a missing or closed index.
wait_if_ongoing boolean

If true, the flush operation blocks until execution when another flush operation is running. If false, Elasticsearch returns an error if you request a flush when another flush operation is running.
