Its much more than that.  For the most part highlighters reduce the query
to a list of terms blindly.  Some do phrases.  They don't really have that
nuanced a view of the query itself.

Its because highlighting is totally decoupled from the actual search
portion of the job - its more like a recheck.  And Lucene isn't built to
cleanly plug the highlighters into the queries.  So they have tons of
instanceof style hacks to get the job done.  Its not super pleasant.
