我想编写一个快速脚本来提醒自己将后续行动项目放在各种 Google 文档中，而不是 Google Drive 中，以便从 API list() 中受益。但是，followup:actionitems由于搜索词未知，搜索查询似乎无法与 API 配合使用。它返回 400 错误。

例如，这样做：

results = service.files().list(q="followup:actionitems",
                                   pageSize=50,
                                   pageToken=page_token,
                                   fields="nextPageToken, files(id, name)").execute()

结果：

Traceback (most recent call last):
  File "./reminder.py", line 49, in <module>
    main()
  File "./reminder.py", line 38, in main
    fields="nextPageToken, files(id, name)").execute()
  File "/home/x/.virtualenvs/gdocs-followup-reminder-7WeAWiqi/lib/python3.7/site-packages/googleapiclient/_helpers.py", line 130, in positional_wrapper
    return wrapped(*args, **kwargs)
  File "/home/x/.virtualenvs/gdocs-followup-reminder-7WeAWiqi/lib/python3.7/site-packages/googleapiclient/http.py", line 856, in execute
    raise HttpError(resp, content, uri=self.uri)
googleapiclient.errors.HttpError: <HttpError 400 when requesting https://www.googleapis.com/drive/v3/files?q=followup%3Aactionitems&pageSize=50&fields=nextPageToken%2C+files%28id%2C+name%29&alt=json returned "Invalid Value">

我是不是遗漏了什么？用法不对？还是说以后有计划提供此功能？
