[rules-users] string replace collision problem

[FrankVhh]

I am sorry, but that would not work either. The first rule would not catch
those sentences that have both S and SF in them.

You will have to work in three steps and use an intermediate value.

1. Change SF to Q
2. Change S to VOL
3. Change Q to S

Separate your steps by using ruleflow or agenda-groups. Make sure to update
your WM after every change.

Sorry for the confusion.

Regards,
Frank
