Mike Sokolov commented on LUCENE-8273:
--------------------------------------
Also - along the lines of making general purpose TokenFilter compositional
tools, I think this general idea can be extended to handle multiple branches,
so not just an 'if' statement, but we can also have a 'switch' statement that
invokes one of a set of different wrapped filters, although if we did that, it
should be a separate thing from this I think.

> Spinoff of LUCENE-8265. It would be useful to be able to wrap a TokenFilter
> in such a way that it could optionally be bypassed based on the current state
> of the TokenStream. This could be used to, for example, only apply
> WordDelimiterFilter to terms that contain hyphens.
