.. note::
|
|
|
|
Due to server-side limitations, you can only get up to around ~10,000 messages and each message
|
|
retrieved will not have any *reply_to_message* field.
|
|
|
|
Parameters:
|
|
query (``str``):
|
|
Text query string.
|
|
|
|
limit (``int``, *optional*):
|
|
Limits the number of messages to be retrieved.
|
|
By default, no limit is applied and all messages are returned.
|
|
|
|
Returns:
|
|
``Generator``: A generator yielding :obj:`Message` objects.
|
|
|
|
Example:
|
|
.. code-block:: python
|
|
|
|
# Search for "pyrogram". Get the first 420 results
|
|
for message in app.search_global("pyrogram", limit=420):
