        # Get tokens from text analysis.
        # The analyze API performs analysis on a text string and returns the resulting tokens.
        # Generating excessive amount of tokens may cause a node to run out of memory.
        # The `index.analyze.max_token_count` setting enables you to limit the number of tokens that can be produced.
        # If more than this limit of tokens gets generated, an error occurs.
        # The `_analyze` endpoint without a specified index will always use `10000` as its limit.
        #
        # @option arguments [String] :index Index used to derive the analyzer.
        #  If specified, the `analyzer` or field parameter overrides this value.
        #  If no index is specified or the index does not have a default analyzer, the analyze API uses the standard analyzer.
        # @option arguments [Boolean] :error_trace When set to `true` Elasticsearch will include the full stack trace of errors
        #  when they occur.
        # @option arguments [String] :filter_path Comma-separated list of filters in dot notation which reduce the response
        #  returned by Elasticsearch.
        # @option arguments [Boolean] :human When set to `true` will return statistics in a format suitable for humans.
        #  For example `"exists_time": "1h"` for humans and
        #  `"eixsts_time_in_millis": 3600000` for computers. When disabled the human
        #  readable values will be omitted. This makes sense for responses being consumed
        #  only by machines.
        # @option arguments [Boolean] :pretty If set to `true` the returned JSON will be "pretty-formatted". Only use
        #  this option for debugging only.
        # @option arguments [Hash] :headers Custom HTTP headers
        # @option arguments [Hash] :body request body
        #
