AND and OR in si configuresandbox --scope=... expression?

How can I configure a sandbox scope like "path:AAA OR path:BBB OR name:frolic.txt"?

The Help file for the 2009 MKS Integrity GUI says that the "si configuresandbox" command can be used to implement scopes using a combination of logical AND or OR operators, but the si manpage we have doesn't seem to mention --scope and the help text from "si configuresandbox -?" indicates some syntaxes like "name:value" and "path:<expression>" with no hints about how to apply logical operators.

Pointers to documentation I missed are appreciated!

Thanks,

Barrie
