Subject [jira] [Commented] (LUCENE-8273) Add a ConditionalTokenFilter
Date Thu, 26 Apr 2018 10:31:00 GMT

Robert Muir commented on LUCENE-8273:
-------------------------------------

So you mean that the problem is not related to buffering state, its more that it only expects
one call to incrementToken() and does the wrong thing if it gets called additional times?
Sorry I'm slow here, i wanted to play with the patch last night but didn't have the time.

> 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.
