Description
The index selection mechanism in QueryImpl may lead to the wrong index to be picked up in case different indexes return same (or very close) costs.
As a remedy we can set cost overrides, change queries or index definitions.
However to speed up identification of such problematics situations it'd be good to have a line in the (debug) logs reporting when for a particular query a number of indexes have same or very close costs (in the order of 10^-1). This would give a first pointer to such possible problematic situations to be inspected.
