> {{SolrIndexSearcher}} leaks are a notable cause of garbage collection issues
> in codebases with custom components.
> So it is useful to be able to access monitoring information about what
> searchers are currently open, and in turn access their stats e.g.
> {{openedAt}}.
> This can be nested via {{SolrCore#getStatistics()}} which has a
> {{_searchers}} collection of all open searchers.
