Anyone know of a twitter app that lets you search one of your followers tweets?

For example, lets say I'm following 'John Doe' and he tweets all the time but I want to find the tweet from a few weeks back in which he mentioned seeing Inception. Is there any app that would let me specifically search only his tweets or possibly only the tweets of just the people I follow? (that would at least narrow it down from a standard twitter search).
