Adding live search of groups to my Elgg site (like Google Suggest)

I am trying to add a google-suggest-like search to my Elgg site. When a user starts typing their search query and reaches at least three characters, I would like to suggest the group titles that match the names they are looking for.

While I doubt there is an exact plugin match for this out there, I was hoping to find a live search or search suggestion plugin that I could customize to only search group titles. Could anyone point me to something like this?

Thanks.
