anchor.diff:  {ccs} (CCS) requests. See <<ccs-network-delays>>. Defaults to `true`.

  -  (Optional, string) A comma-separated list of fields to return as the docvalue
  -  representation of a field for each hit.

  `ignore_throttled`::
    (Optional, boolean) If `true`, concrete, expanded or aliased indices will be
    ignored when frozen. Defaults to `false`.

  `max_concurrent_shard_requests`::
    (Optional, integer) Defines the number of concurrent shard requests per node
    this search executes concurrently. This value should be used to limit the
    impact of the search on the cluster in order to limit the number of concurrent
    shard requests. Defaults to `5`.
  
  `pre_filter_shard_size`::
    (Optional, integer) Defines a threshold that enforces a pre-filter roundtrip
    to prefilter search shards based on query rewriting if the number of shards
    the search request expands to exceeds the threshold. This filter roundtrip can
    limit the number of shards significantly if for instance a shard can not match
    any documents based on its rewrite method ie. if date filters are mandatory
    to match but the shard bounds and the query are disjoint.
    When unspecified, the pre-filter phase is executed if any of these conditions is met:
      - The request targets more than `128` shards.
      - The request targets one or more read-only index.
      - The primary sort of the query targets an indexed field.
  
  `preference`::
    (Optional, string) Specifies the node or shard the operation should be
    performed on. Random by default.

  `rest_total_hits_as_int`::
  (Optional, boolean) Indicates whether hits.total should be rendered as an
  integer or an object in the rest search response. Defaults to `false`.
  
  `routing`::
  (Optional, <<time-units, time units>>) Specifies how long a consistent view of
  the index should be maintained for scrolled search.
