Adrien Grand commented on LUCENE-8292:
--------------------------------------
Indeed these methods need to be overridden explicitly if you want them to be
used.
In general, we do not delegate methods that have a default implementation
because the default implementation is correct regardless of what the wrapper
class does. Overriding these methods in FilterTermsEnum to delegate to the
wrapped instance would make room for bugs by requiring more methods to be
overridden for the wrapper to be correct.

>
> FilterLeafReader#FilterTermsEnum wraps another TermsEnum and delegates many
> methods.
> It misses some seekExact() methods, thus it is not possible to the delegate
> to override these methods to have specific behavior (unlike the TermsEnum API
> which allows that).
> The fix is straightforward: simply override these seekExact() methods and
> delegate.
