I don't think that these are necessary. I was just quoting from the
various prior proposals rather than advocating them.

Wouldn't that be two separate databases?
And hence my proposed 'related' tag for explain.
Or if it's indexes then it would be the one specified in the searchClause.

I thought that termFrequency was how many matches a search using the
attribute combination would return for the term. And you would need to
use the anywhere index to find the count of the term in any index.

No idea when it's useful to know how many terms are in an index. Even for
our trick of scanning from beginning to end to create a view of the
database it's not useful as we have to go through it all anyway.
