I'm not sure. Maybe it wouldn't be too difficult.

You could do e.g.:

1 fetch * bodystructure 

But this assumes that client is interested of bodystructure, otherwise
it pollutes the cache with an unnecessary field. You could also check

1 search * body asdf

updates cache. I vaguely remember that it does, but I'm not sure.
idxview anyway shows what exists in cache.

With most clients, yes.
