# Performs an update on every document in the index without changing the source,
# for example to pick up a mapping change.
#
# @option arguments [List] :index A comma-separated list of index names to search; use `_all` or empty string to perform the operation on all indices
# @option arguments [String] :analyzer The analyzer to use for the query string
# @option arguments [Boolean] :analyze_wildcard Specify whether wildcard and prefix queries should be analyzed (default: false)
# @option arguments [String] :default_operator The default operator for query string query (AND or OR) (options: AND, OR)
# @option arguments [String] :df The field to use as default where no field prefix is given in the query string
# @option arguments [Number] :from Starting offset (default: 0)
# @option arguments [Boolean] :ignore_unavailable Whether specified concrete indices should be ignored when unavailable (missing or closed)
# @option arguments [Boolean] :allow_no_indices Whether to ignore if a wildcard indices expression resolves into no concrete indices. (This includes `_all` string or when no indices have been specified)
# @option arguments [String] :conflicts What to do when the update by query hits version conflicts? (options: abort, proceed)
# @option arguments [String] :expand_wildcards Whether to expand wildcard expression to concrete indices that are open, closed or both. (options: open, closed, hidden, none, all)
# @option arguments [Boolean] :lenient Specify whether format-based query failures (such as providing text to a numeric field) should be ignored
# @option arguments [String] :pipeline Ingest pipeline to set on index requests made by this action. (default: none)
# @option arguments [String] :preference Specify the node or shard the operation should be performed on (default: random)
# @option arguments [String] :q Query in the Lucene query string syntax
# @option arguments [List] :routing A comma-separated list of specific routing values
# @option arguments [Time] :scroll Specify how long a consistent view of the index should be maintained for scrolled search
# @option arguments [String] :search_type Search operation type (options: query_then_fetch, dfs_query_then_fetch)
# @option arguments [Time] :search_timeout Explicit timeout for each search request. Defaults to no timeout.
# @option arguments [Number] :max_docs Maximum number of documents to process (default: all documents)
# @option arguments [List] :sort A comma-separated list of <field>:<direction> pairs
# @option arguments [List] :_source True or false to return the _source field or not, or a list of fields to return
# @option arguments [List] :_source_excludes A list of fields to exclude from the returned _source field
# @option arguments [List] :_source_includes A list of fields to extract and return from the _source field
# @option arguments [Number] :terminate_after The maximum number of documents to collect for each shard, upon reaching which the query execution will terminate early.
# @option arguments [List] :stats Specific 'tag' of the request for logging and statistical purposes
# @option arguments [Boolean] :version Specify whether to return document version as part of a hit
# @option arguments [Boolean] :version_type Should the document increment the version number (internal) on hit or not (reindex)
# @option arguments [Boolean] :request_cache Specify if request cache should be used for this request or not, defaults to index level setting
# @option arguments [Boolean] :refresh Should the affected indexes be refreshed?
# @option arguments [Time] :timeout Time each individual bulk request should wait for shards that are unavailable.
# @option arguments [String] :wait_for_active_shards Sets the number of shard copies that must be active before proceeding with the update by query operation. Defaults to 1, meaning the primary shard only. Set to `all` for all shard copies, otherwise set to any non-negative value less than or equal to the total number of copies for the shard (number of replicas + 1)
# @option arguments [Number] :scroll_size Size on the scroll request powering the update by query
# @option arguments [Boolean] :wait_for_completion Should the request should block until the update by query operation is complete.
# @option arguments [Number] :requests_per_second The throttle to set on this request in sub-requests per second. -1 means no throttle.
# @option arguments [Number|string] :slices The number of slices this task should be divided into. Defaults to 1, meaning the task isn't sliced into subtasks. Can be set to `auto`.
# @option arguments [Hash] :headers Custom HTTP headers
# @option arguments [Hash] :body The search definition using the Query DSL
