I'm trying to figure out a way to use Twitter Advanced Search to find only tweets containing polls.
Ideally, there should have been a designated filter operator like filter:polls but it doesn't exist.
Any ideas on how to do it in another way?
Going off Joost C's answer, here's a link that searches all of those at once using OR's:
Here's the same, but filtered to people you follow ("pf=on" query parameter):
To find polls containing 2, 3 or 4 choices, either text or image polls, use:
card_name:poll2choice_text_only
card_name:poll3choice_text_only
card_name:poll4choice_text_only
card_name:poll2choice_image
card_name:poll3choice_image
card_name:poll4choice_image
