how to search for old activity on facebook ticker?

[AzteC]

A friend of mine commented on a really cool music video from some random page last year and I'm trying to find it so I can see it again. I remember I found it because it came up that she commented through my ticker feed. does anybody know how to sort through old activity on the ticker or a friend's profile?

You cant search for a post in facebook ticker. If she had commented then it will be there in her activity log. if you liked it then it will show in your activity log too.
