+   *  comparison operators are: `=`, `<`, `>`, `<=`, `>=`.
+   *  `customer` is required and is used to indicate which customer
+   *  to fetch spaces from. `customers/my_customer` is the only supported value.
+   *  `display_name` only accepts the `HAS` (`:`) operator. The text to
+   *  match is first tokenized into tokens and each token is prefix-matched
+   *  case-insensitively and independently as a substring anywhere in the space's
+   *  `display_name`. For example, `Fun Eve` matches `Fun event` or `The
+   *  evening was fun`, but not `notFun event` or `even`.

+   *  (https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces#Space.HistoryState)
+   *  field of a `space` resource.
+   *  `space_type` is required and the only valid value is `SPACE`.
+   *  Across different fields, only `AND` operators are supported. A valid
+   *  example is `space_type = "SPACE" AND display_name:"Hello"` and an invalid
+   *  example is `space_type = "SPACE" OR display_name:"Hello"`.
+   *  Among the same field,
+   *  `space_type` doesn't support `AND` or `OR` operators.
+   *  `display_name`, 'space_history_state', and 'external_user_allowed' only
+   *  support `OR` operators.
+   *  `last_active_time` and `create_time` support both `AND` and `OR` operators.
+   *  `AND` can only be used to represent an interval, such as `last_active_time
+   *  < "2022-01-01T00:00:00+00:00" AND last_active_time >
+   *  "2023-01-01T00:00:00+00:00"`.

+   *
+   *   This method currently only supports admin access, thus only `true` is
+   *   accepted for this field.
+   * @param {number} request.pageSize
+   *   The maximum number of spaces to return. The service may return fewer than
+   *   this value.
+   *
+   *   If unspecified, at most 100 spaces are returned.
+   *
+   *   The maximum value is 1000. If you use a value more than 1000, it's
+   *   automatically changed to 1000.
+   * @param {string} request.pageToken
+   *   A token, received from the previous search spaces call. Provide this
+   *   parameter to retrieve the subsequent page.
+   *
+   *   When paginating, all other parameters provided should match the call that
+   *   provided the page token. Passing different values to the other parameters
+   *   might lead to unexpected results.
+   * @param {string} request.query
+   *   Required. A search query.
+   *
+   *   You can search by using the following parameters:
+   *
+   *   - `create_time`
+   *   - `customer`
+   *   - `display_name`
+   *   - `external_user_allowed`
+   *   - `last_active_time`
+   *   - `space_history_state`
+   *   - `space_type`
+   *
+   *   `create_time` and `last_active_time` accept a timestamp in
+   *   [RFC-3339](https://www.rfc-editor.org/rfc/rfc3339) format and the supported
+   *   comparison operators are: `=`, `<`, `>`, `<=`, `>=`.
+   *
+   *   `customer` is required and is used to indicate which customer
+   *   to fetch spaces from. `customers/my_customer` is the only supported value.
+   *
+   *   `display_name` only accepts the `HAS` (`:`) operator. The text to
+   *   match is first tokenized into tokens and each token is prefix-matched
+   *   case-insensitively and independently as a substring anywhere in the space's
+   *   `display_name`. For example, `Fun Eve` matches `Fun event` or `The
+   *   evening was fun`, but not `notFun event` or `even`.
+   *
+   *   `external_user_allowed` accepts either `true` or `false`.
+   *
+   *   `space_history_state` only accepts values from the [`historyState`]
+   *   (https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces#Space.HistoryState)
+   *   field of a `space` resource.
+   *
+   *   `space_type` is required and the only valid value is `SPACE`.
+   *
+   *   Across different fields, only `AND` operators are supported. A valid
+   *   example is `space_type = "SPACE" AND display_name:"Hello"` and an invalid
+   *   example is `space_type = "SPACE" OR display_name:"Hello"`.
+   *
+   *   Among the same field,
+   *   `space_type` doesn't support `AND` or `OR` operators.
+   *   `display_name`, 'space_history_state', and 'external_user_allowed' only
+   *   support `OR` operators.
+   *   `last_active_time` and `create_time` support both `AND` and `OR` operators.
+   *   `AND` can only be used to represent an interval, such as `last_active_time
+   *   < "2022-01-01T00:00:00+00:00" AND last_active_time >
+   *   "2023-01-01T00:00:00+00:00"`.
+   *
+   *   The following example queries are valid:
+   *
+   *   ```
+   *   customer = "customers/my_customer" AND space_type = "SPACE"
+   *
+   *   customer = "customers/my_customer" AND space_type = "SPACE" AND
+   *   display_name:"Hello World"
+   *
+   *   customer = "customers/my_customer" AND space_type = "SPACE" AND
+   *   (last_active_time < "2020-01-01T00:00:00+00:00" OR last_active_time >
+   *   "2022-01-01T00:00:00+00:00")
+   *
+   *   customer = "customers/my_customer" AND space_type = "SPACE" AND
+   *   (display_name:"Hello World" OR display_name:"Fun event") AND
+   *   (last_active_time > "2020-01-01T00:00:00+00:00" AND last_active_time <
+   *   "2022-01-01T00:00:00+00:00")
+   *
+   *   customer = "customers/my_customer" AND space_type = "SPACE" AND
+   *   (create_time > "2019-01-01T00:00:00+00:00" AND create_time <

+   *   (space_history_state = "HISTORY_ON" OR space_history_state = "HISTORY_OFF")
+   *   ```
+   * @param {string} [request.orderBy]
+   *   Optional. How the list of spaces is ordered.
+   *
+   *   Supported attributes to order by are:
+   *
+   *   - `membership_count.joined_direct_human_user_count` — Denotes the count of
+   *   human users that have directly joined a space.
+   *   - `last_active_time` — Denotes the time when last eligible item is added to
+   *   any topic of this space.
+   *   - `create_time` — Denotes the time of the space creation.
+   *
+   *   Valid ordering operation values are:
+   *
+   *   - `ASC` for ascending. Default value.
+   *
+   *   - `DESC` for descending.
+   *
+   *   The supported syntax are:

+   *   - `membership_count.joined_direct_human_user_count DESC`
+   *   - `membership_count.joined_direct_human_user_count ASC`
+   *   - `last_active_time DESC`
+   *   - `last_active_time ASC`
+   *   - `create_time DESC`
+   *   - `create_time ASC`
+   * @param {object} [options]
+   *   Call options. See {@link https://googleapis.dev/nodejs/google-gax/latest/interfaces/CallOptions.html|CallOptions} for more details.
+   * @returns {Promise} - The promise which resolves to an array.
+   *   The first element of the array is Array of {@link protos.google.chat.v1.Space|Space}.
+   *   The client library will perform auto-pagination by default: it will call the API as many
+   *   times as needed and will merge results from all the pages into this array.
+   *   Note that it can affect your quota.
+   *   We recommend using `searchSpacesAsync()`

+   *   `AND` can only be used to represent an interval, such as `last_active_time

+   *   ```
+   * @param {string} [request.orderBy]
+   *   Optional. How the list of spaces is ordered.
+   *
+   *   Supported attributes to order by are:
+   *
+   *   - `membership_count.joined_direct_human_user_count` — Denotes the count of
+   *   human users that have directly joined a space.
+   *   - `last_active_time` — Denotes the time when last eligible item is added to
+   *   any topic of this space.
+   *   - `create_time` — Denotes the time of the space creation.
+   *
+   *   Valid ordering operation values are:
+   *
+   *   - `ASC` for ascending. Default value.
+   *
+   *   - `DESC` for descending.
+   *
+   *   The supported syntax are:
+   *
+   *   - `membership_count.joined_direct_human_user_count DESC`
+   *   - `membership_count.joined_direct_human_user_count ASC`
+   *   - `last_active_time DESC`
+   *   - `last_active_time ASC`
+   *   - `create_time DESC`
+   *   - `create_time ASC`
+   * @param {object} [options]
+   *   Call options. See {@link https://googleapis.dev/nodejs/google-gax/latest/interfaces/CallOptions.html|CallOptions} for more details.
+   * @returns {Object}
+   *   An iterable Object that allows {@link https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols | async iteration }.
+   *   When you iterate the returned iterable, each element will be an object representing
+   *   {@link protos.google.chat.v1.Space|Space}. The API will be called under the hood as needed, once per the page,
+   *   so you can stop the iteration when you don't need more results.
+   *   Please see the {@link https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination | documentation }
+   *   for more details and examples.
