I have some Carttypes:
Intention, Field, Scope related as follows:
An Intention has a field (+field}, which is a pointer to a Field card
A Scope also has a field (+field), also a pointer to a field.
On on Intention, I want the *options to be a search returning The scopes with the same +field value as the Intention.
It seems to have the rules matching, I made it a select with an Intention+scope+*type_plus_right+*input rule, but may search isn't quite right, I have:
{"type":"Scope","refer_to":[{"append":"field"},"_left+field"]}
