Twitter for Android received its first update in almost two months today, though it's a rather focused one: the 'search' experience has been substantially revamped. Now, instead of merely getting people and tweets results tabs, you get a mixed feed of results that can be refreshed by pulling down.
The results, as far as I can tell, are organized in three ways: tweets, people, and top tweets. If there are any Top Tweets for a particular search term, you'll see those tweets on top of the general tweet results. Above those will be the people results. Pulling down from the top of the results page will give you the newest tweets matching your search, up to about the last 15 seconds.
