A nice way to analyse the need or unneed of indexes (maybe there are
some that we could yet add for more performance) it would be nice to try
to make a "summary" of all potential SQL-queries that indexed search
might do. Maybe this can be traced at TYPO3_DB level.

That knowledge would allow us to optimize on index level.

Cheers,
