  // - `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"`.

  //
  // ```
  // customer = "customers/my_customer" AND space_type = "SPACE"
  //
  // customer = "customers/my_customer" AND space_type = "SPACE" AND
  // display_name:"Hello World"
