Global Search and 3.1

Installed latest Global Search plug in from WPMU, Activated, and used the back end style features. The page was generated and the search form was on the page. However, when I search for known words in various blogs in the network, including the local one, there are never results. I search on a period or blank line, same results.

If it is based on the plug in by aliciagh, if there is a clash with 3.1 I am sure she'd like a heads up on the fix.
