[rules-users] write a rule file, longest matching?

[Wolfgang Laun]

Rather than examples, you might have posted the requirement itself,
i.e., whatever was in your mind when you composed the example and
the data. Is the number of matching attributes a, b, c, d the deciding
factor? What happens if the inserted fact matches a and b of list#1 and
c and d of list#2? And so on.

This *seems* to be a variation of what I call "classification problem", see

but it's hard to tell from the example.
