"""Search for text and media messages inside a specific chat.
If you want to get the messages count only, see :meth:`~pyrogram.Client.search_messages_count`.
.. include:: /_includes/usable-by/users.rst
Parameters:
chat_id (``int`` | ``str``):
Unique identifier (int) or username (str) of the target chat.
For your personal cloud (Saved Messages) you can simply use "me" or "self".
For a contact that exists in your Telegram address book you can use his phone number (str).
query (``str``, *optional*):
Text query string.
Required for text-only messages, optional for media messages (see the ``filter`` argument).
When passed while searching for media messages, the query will be applied to captions.
Defaults to "" (empty string).
offset (``int``, *optional*):
Sequential number of the first message to be returned.
Defaults to 0.
filter (:obj:`~pyrogram.enums.MessagesFilter`, *optional*):
Pass a filter in order to search for specific kind of messages only.
Defaults to any message (no filter).
limit (``int``, *optional*):
Limits the number of messages to be retrieved.
By default, no limit is applied and all messages are returned.
from_user (``int`` | ``str``, *optional*):
Unique identifier (int) or username (str) of the target user you want to search for messages from.
Returns:
``Generator``: A generator yielding :obj:`~pyrogram.types.Message` objects.
Example:
.. code-block:: python
from pyrogram import enums
# Search for text messages in chat. Get the last 120 results
async for message in app.search_messages(chat_id, query="hello", limit=120):
print(message.text)
# Search for pinned messages in chat
async for message in app.search_messages(chat_id, filter=enums.MessagesFilter.PINNED):
print(message.text)
# Search for messages containing "hello" sent by yourself in chat
async for message in app.search_messages(chat, "hello", from_user="me"):
print(message.text)
