Say I wanted to see all the tweets in my feed from @MickeyMouse. Is there a way I can search for a particular person's tweets in my feed? I know of course about searching for a person's page and about filtering by group but this would be just for one person's tweets in my feed who isn't in a group.
the only way I know it - you just have to go to that person's account and scroll to the tweets you need.
if you're using an adroid phone you can download twitter app client called tweetdeck. it can let you filter your feed based on keywords and also tweethandles. tweetdeck is also available on desktop version. just go to tweetdeck.com if I am not mistaken. hope this helps
