> Resource usage by a query is not limited to the actual search within {{QueryComponent}}. Other components invoked by {{SearchHandler}} may significantly contribute to this usage, either before or after the {{QueryComponent}}.
> Those components that already use {{QueryTimeout}} either directly or indirectly will properly observe the limits and terminate if needed. However, other components may be expensive or misbehaving but fail to observe the limits imposed on the end-to-end query processing.
> One such obvious place where we could add this check is where the {{SearchHandler}} loops over {{SearchComponent}-s - it should call explicitly {{QueryLimits.shouldExit()}} to ensure that even if previously executed component ignored the limits they will be still enforced at the {{SearchHandler}} level. There may be other places like this, too.
