Subject [jira] Updated: (SOLR-1362) WordDelimiterFilter position increment bug

Yonik Seeley updated SOLR-1362:
-------------------------------

    Attachment: SOLR-1362.patch

I had implemented the "remove normal posIncr" this morning - just got around to adding a test
though.  Seems to work - can you see if this matches your expectations?

I think about it like this:  position increments serve two purposes... to signify the normal
case of tokens being adjacent to each other, and to separate groups of tokens.  In the former
case, it makes sense to completely consume the delimiter and keep the resulting tokens next
to eachother.  In the later case, we want to preserve the logical separation.

> WordDelimiterFilter sometimes assigns high position increment values, which inhibits
phrase matches.
> If this is a feature and not a bug please change the issue type, and I will change the
patch to propose this as an option...
