"""Search messages globally from all of your chats.
.. 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``, *optional*):
Text query string.
Use "@" to search for mentions.
filter (``str``, *optional*):
Pass a filter in order to search for specific kind of messages only:
- ``"empty"``: Search for all kind of messages (default).
- ``"photo"``: Search for photos.
- ``"video"``: Search for video.
- ``"photo_video"``: Search for either photo or video.
- ``"document"``: Search for documents (generic files).
- ``"url"``: Search for messages containing URLs (web links).
- ``"animation"``: Search for animations (GIFs).
- ``"voice_note"``: Search for voice notes.
- ``"audio"``: Search for audio files (music).
- ``"chat_photo"``: Search for chat photos.
- ``"audio_video_note"``: Search for either audio or video notes.
- ``"video_note"``: Search for video notes.
- ``"location"``: Search for location messages.
- ``"contact"``: Search for contact messages.
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:`~pyrogram.types.Message` objects.
Example:
.. code-block:: python
# Search for "pyrogram". Get the first 420 results
for message in app.search_global("pyrogram", limit=420):
print(message.text)
# Search for recent photos from Global. Get the first 69 results
for message in app.search_global(filter="photo", limit=69):
print(message.photo)
