[rules-users] "Or" and Collect

In my ongoing efforts to abuse Drools syntax, I would like to write rules like this: rule "severe bugs for which a member of your group is dev or support owner" when $group : UserGroup( ) $badBugs : List() from collect( Bug( (devOwner memberOf $group or supportOwner memberOf $group), severity == "hair-on-fire" ) then $group.runAroundInStarkRavingPanicOver($badBugs) end Will that work? Is that the right syntax? Will it be performant if I've got 10000 Bugs and 1000 UserGroups? According to Mark's "What's New in JBoss Rules 4.0" presentation, you can use && and || without subrule generation, and I have a vague memory of seeing something about "and" & "or" as well, but I can't remember where I saw it.
