This means that every chat will be handled *except* those specified in ``users`` which will be ignored if ``blacklist_users=True``. pattern (`str`, `callable`, `Pattern`, optional): If set, only queries matching this pattern will be handled. You can specify a regex-like string which will be matched against the message, a callable function that returns `True` if a message is acceptable, or a compiled regex pattern.

Sending more will raise ``ResultsTooMuchError``, and you should consider using `next_offset` to paginate them. cache_time (`int`, optional): For how long this result should be cached on the user's client.
