Filter: Allow to filter by key/value search term

This is a feature request.

UseCase

I would like to monitor a larger area like whole Berlin for everything that has to do with bike-infrastructure.

Right now, I can create a filter for all changes for Berlin. And subscribe to this via RSS.

But I cannot filter this based on the OSM tags that where used in the changesets.

Idea

Add one or two fields to the filter view:

Filter to changesets that use this keyword inside one of the changesets OSM keys:
[_____] (enter keywords separated by comma)

Filter to changesets that use this keyword inside one of the changesets OSM key-values:
[_____] (enter keywords separated by comma)

Example 1:

I filter for key-keyword cycle to find changesets that use keys like cycleway or bicycle. (OSM Wiki)

Example 2:

I filter for “key value”-keyword bicycle to find changesets that use keys like amenity=bicycle_parking, amenity=bicycle_rental or shop=bicycle. (OSM Wiki)

After learning more about osmcha at SOTM Heidelberg

Do you talk about Using OSMCha to understand bad edits? Unfortunately this talk wasn’t recorded.

The UI only knows about the changeset at first

Yes, the UI probably know nothing about changesets content. It need also changes in OsmCha backend.
