Comment (by Ipstenu):

 There's a plugin for that, sort of. It collects all posts from all sites
 onto a 'tags' blog and you can search that. Clicking on the links sends
 you back to the 'real' source.

 The reason there isn't a query across all sites is because of how
 ginourmous and horrific that would be when you think about it scaling up.
 Searching all the wp_x_posts tables, combining, sorting, scanning, and
 then outputting? Yikes.
