Previously, lower was better, and higher was worse. But really we want
the scores to be based primarily around the index sizes, which can
grow to be very large, so a maximum score is hard to determine.
Instead, start with the index size, and then divide to make it smaller
based on how "useful" the equation terms will be in searching it.
Improves the performance of queries like those in #19080; according
to humdinger's testing, the query with the most expensive term first
went from ~2.0s execution time down to ~0.7s, same as the query with
the least expensive term first.
