Update Searcher Search query

The Search method for update searcher allows you to specify a criteria
string. Part of that allows you to specify the type of update you are
searching for. The SDK gives examples of Driver and Software.

"Software" is a bit too generic for my needs - I want to limit the search to
critical and security updates only. What would be the correct strings to use
for these?

Thanks.

Is there anyone from Microsoft reading this that can answer this query? I've
tried emailing the SDK people but the email address bounces.

Is there a list of specific terms that work? I've tried changing the text to
Updates or Critical and I get an error back from the method.
