Automatically create Mango indexes

Just throwing the idea...

I was wondering if it could be possible to create the index whenever a query is made. This could be an option within CouchDB whenever it receives a query and can't find an index, it would create it.

What do you think?

Review CouchDB's Mango query and index handling to understand where a missing-index decision is made. The issue proposes automatic index creation but does not name files, tests, expected behavior, or acceptance criteria, so the scope and definition of done would need to be agreed before implementation.
