Ok, I have found a solution. 1. First search for `type:node tags:0` 2. Then search for `child parent type:node` and select `remove from selection`. ## Explanation ## 1. Searches for all nodes which have zero tags (that includes many nodes that are part of ways). 2. Then search for nodes which have a parent (a way). And then the child of this parent (the nodes that are part of a way). By removing thess these from the selection, we have only the unused orphan nodes left. Voilà.
