I think it's got something to do with Document.invertDocument().
When I reverse the words in the phrase, the other document matches the
phrase query.

I concur that it appears to be a bug. It is unlikely folks use Lucene
like this too much though - there probably are not too many scenarios
where combining things into a single String or Reader is a burden.
I'm interested to know where in the code this oddity occurs so I can
understand it more. I did a brief bit of troubleshooting but haven't
figured it out yet. Something in DocumentWriter I presume.
