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:


xxxxxxxxxx
 
<;

The input set of the recurse up statement can be chosen with the usual prefix notation:


xxxxxxxxxx
 
.a <;

The result set of the recurse up statement can be redirected with the usual postfix notation:


xxxxxxxxxx
 
< ->.b;

Of course, you can also change both:


xxxxxxxxxx
 
.a < ->.b;

xxxxxxxxxx
 
(
  node(47.0678,15.440,47.069,15.444);
  <;
);
out;
