Returns:
``Generator``: A generator yielding :obj:`~pyrogram.types.Message` objects.
Example:
.. code-block:: python
# Search for text messages in @pyrogramchat. Get the last 333 results
for message in app.search_messages("pyrogramchat", query="dan", limit=333):
print(message.text)
# Search for pinned messages in @pyrogramchat
for message in app.search_messages("pyrogramchat", filter="pinned"):
print(message.text)
# Search for messages containing "hi" sent by @haskell in @pyrogramchat
for message in app.search_messages("pyrogramchat", "hi", from_user="haskell"):
print(message.text)
