     * input fields.
     *
     * Multi-value fields in the query API take multiple inputs as an array
     * (internally converted to a pipe-delimted string) but with a limit of 500
     * (or 50 for users without apihighlimits).
     * Example: the fields titles, pageids and revids in any query, ususers in
     * list=users.
     *
     * This function allows you to send a query as if this limit didn't exist.
     * The array given to the multi-input field is split into batches and individual
     * queries are sent sequentially for each batch.
     * A promise is returned finally resolved with the array of responses of each
     * API call.
     *
     * The API calls are made via POST instead of GET to avoid potential 414 (URI
     * too long) errors.
     *
     * @param {Object} query - the query object, the multi-input field should
     * be an array
     * @param {string} [batchFieldName=titles] - the name of the multi-input field
     *
     * @returns {Promise<Object[]>} - promise resolved when all the API queries have
     * settled, with the array of responses.
