Mark Lucovsky's been doing more interesting hacking with the AJAX Search API, only this time it's in the context of a weblog: http://ajaxsearch.blogspot.com/

A post on the API's blog explains some of his tweaks and integrations:
  • Google Search form in the sidebar does parallel searches of several indexes, as well as site-restricts
  • Video Search form in the sidebar returns results (and can play them) inline
  • Map Search is scoped/embedded in the sidebar, and can be augmented with searches/favorite places/etc.
  • javascript: URLs can drive the any of the sidebar's Search API modules
