[rules-users] Disabling pattern matching alltogether for set of rules?

[Ingomar Otter]

Folks,
we have a scenario where we are applying rules with complex in their   
LHS at the "end of our rule processing".

Today we just use a low salience to achieve this. Obviously, these    
rules are included in the pattern matching and in the agenda updates  
for all   preceding changes to the WM.
We do quite some changes to the facts during our regular processing  
so  "unnecessary" pattern-matching/agenda updates are performed.
I have looked at rule-flow, agenda-groups etc but one thing I could    
not figure out by studying the documentation:
Which is the (best) way to exclude certain rules from pattern  
matching  (switch them off alltogether) so that we can delay the  
pattern   matching until the facts have stabilized?

    Cheers,
       Ingomar
