allow searching for position in way

[NE2]

For example, I might want to search for firstnode highway=motorway_link child highway=motorway -highway=motorway_junction to find missing motorway_junctions. (firstnode would be like child but require it to be the first node in the way, useful here because the motorway_link is one-way.)

Oh, and naturally this would apply to relations as well.

What about allowing a parameter to the child keyword? If you want to select the first and last node use child:0,-1. Not sure how to allow for a range of nodes. I suppose child:1--2 could technically be parsed to mean all nodes except the ends, but it certainly doesn't look readable.

Your suggestions sounds good to me.

For parsing a range of timestamp, I've chosen / (e.g., 2010-10-05/2011-01-30) recently.

In 5578/josm:

fix #7262 - allow searching for position in way.

The search keyword nth: have been added in order to
search for the n-th member of relations and/or n-th node of ways.
Also, nth%: is supported which searches for every n-th item, respectively.
