Show search index status

If there is a way to indicate the current status of the index.. or the queue for documents/commits waiting to be indexed.

I know it should be magically and instantaneous , but with 2000+ developers and 5000+ repos i need a little more to make sure i know what to say to developers when they say search results are not reflecting their commits.

Bonus points if there is a way (admin or project admin) to 'touch' a repo, to force it to be reindexed
