Recurse Up (<) Improve page
The recurse up standalone query is written as a single less than.
It takes an input set. It produces a result set. Its result set are all the ways that have a node appearing in the input set as a member, all relations that have a node or way from the input set as a member, and all relations that have a way from the result set as members.
Example:
<;
The input set of the recurse up statement can be chosen with the usual prefix notation:
.a <;
The result set of the recurse up statement can be redirected with the usual postfix notation:
< ->.b;
Of course, you can also change both:
.a < ->.b;
