[rules-users] Detecting partial matches

[elmo]

Hi,
   
     Based on what you have given, I agree that you should separate this
into two rules. On a different note, my understanding of partial matches is
you have two different conditions, example age and height of a person. A
person may match the age but does not match the height requirements. If this
is your case, I suggest you keep a score in your object. Ex. if it matches
age, add 50. if it matches height, add 50. a score of 100 would be a full
match while a score of 50 is only a partial match. Then the final rule would
make it easier because you would only check the score. Just a thought.  

Regards,

Elmo
