**In any comparison binary operation involving vectors**, providing the `bool`
modifier changes the behavior in the following ways:
* Vector elements that would be dropped instead have the value `0` and
vector elements that would be kept have the value `1`. (Note that
invalid operations involving histogram samples still return no result rather
than the value `0`.)
* Vector elements which find a match on the other side of the expression but for
which the expression is false instead have the value `0` and vector elements
that do find a match and for which the expression is true have the value `1`.
(Note that elements with no match or invalid operations involving histogram
samples still return no result rather than the value `0`.)
* The metric name is dropped.
If the `bool` modifier is not provided, then the metric name from the left side
