I'm trying to debug single queries in isolation: I'm not interested in how my query is being analyzed (since the fields are all not\_analyzed), but rather in seeing how much time goes on fetch, which caches are hit etc. Is this possible for a specific query?

P.S. I've looked at EXPLAIN, but that seems to be about search-analysis internals. The slow-query log shows me which queries are slow and what of type (query-and-fetch, query-then-fetch etc.) they are, but not about where the time gets spent. Setting log-level to TRACE didn't yield what I was looking for, either.

This isn't currently possible.

I thought as much - thank you for the confirmation!

That looks great. Is it scheduled for a particular release?
