[jira] [Commented] (LUCENE-8308) migrate KeywordRepeatFilter to conditional tokenstreams

    [ https://issues.apache.org/jira/browse/LUCENE-8308?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16472229#comment-16472229 ] 

Robert Muir commented on LUCENE-8308:
-------------------------------------

The other idea in mind being that we extend LUCENE-8273 to support "else" essentially. Then this repeater case would be more transparent/obvious, it fires for both the "if" and the "else".

> we should deprecate KeywordAttribute in favor of LUCENE-8273 which gives the analysis chain a real "if".
> But this isn't straightforward unless we address the KeywordRepeatFilter which sends the token "both ways" down the branch condition. Maybe it can be handled as a subclass.
