[josm-dev] The search engine needs more SQL-like features

[Ævar Arnfjörð Bjarmason]

Sometimes I want JOSM to give me things like "All ways that are a
member of a relation that contains a given key/value pair".

Currently the best I can do is:

1. Search for "type:relation key:value"
2. Select one of the relations
3. Edit it
4. Select the members I want (usually all)
5. I now have what I wanted in the selection dialog

But that's tedious when I have a few hundred relations to go through.

But aside from this specific issue I wanted to start a discussion on
what a hypothetical future improved JOSM search engine should look
like. Could some of these issues be solved by relatively simple
additions ("type:way in:(type:relation key:value)" or would that be a
bad reinvention of more sophisticated query languages?
