Infact, you can make eval(true) in one of them, and put the salience property higher than the non-default one,
Let's say by example that your split node has two outgoings, and A is the default:
-A with eval(true) and priority 1000
-B with Url(score >90) priority 1
 
But it's described in the drools flow documentation... I suggest you to read it...

Objet : [rules-users] how to write a single constraint in split node

Hi,

i'm kind of new to Drools and still trying to build a simple process.
I'm trying to understand if (and how) it is possible to write a 'rule' constraint inside a split node that won't require 
writing the opposite rule for the 2nd target node.

for e.g. if i have a split node with 2 target nodes, 
and my 1st constraint is "Url( score > 90)" -> this will take me to target node 1.
i want that split node will know to go target node 2 in case the score is less or equal to 90,
without the need to explicitly write the 2nd constraint as "Url (score <= 90)".

is that possible?
