Fritz at RedMountain is of the opinion that Google BlogSearch is already able to execute a tag search, using the tag: modifier. As he points out, they'll have a hard time finding tags at the end of posts from any blog that publishes a partial feed, since the feed will snip the tags. Another incentive for bloggers to publish full feeds!!
On a related matter: I have not been able to properly duplicate this experiment since I found that this blog was set to publish a partial feed in atom, which probably means that the feedburner feed that is set for full publication was only pulling a partial feed as it's source & so wasn't doing what I thought it was doing. I switched it up to full feed & hopefully you'll see more Freshblog goodies in your feedreaders, & google blogsearch will see my tags, & I will be able to duplicate this discovery as soon as Freshblog's been crawled.
While we wait, anyone who would care to re-create Fritz's experiment, & thusly expose one of the surprises that we have coming when blogsearch gets out of beta, should please post their experiences & results in the comments!!
Oh, and hey, publish a full feed already, would you? ;-)
