Hi,

I’ve tried using timeAllowed in both Solr 8 and Solr 9, but it appears that
the highlight processing time is not included within the timeAllowed value.

BTW, according to the reference guide under 'Major Changes in Solr 9', It
seems to imply that in Solr versions below 9.3, timeAllowed could be used
to cancel not only the core search processing but also other components
such as spellcheck and faceting.
https://solr.apache.org/guide/solr/latest/upgrade-notes/major-changes-in-solr-9.html#use-of-timeallowed

```
use of timeAllowedQuery timeouts with timeAllowed are implemented
differently. It should be faster albeit have less fidelity – will not
timeout a query outside of core query processing (e.g. won’t cancel
spellcheck or faceting). Use solr.useExitableDirectoryReader to use the
previous behavior. Please share your experience with Solr developers! The
previous behavior should not be enabled if timeAllowed isn’t used because
unfortunately its performance tax is now imposed on all queries, even those
without timeAllowed.
```

Any ideas please?
