ShingleFilter has nothing to do with phrase queries (other than the fact =
that it can be used to replace them in some circumstances).

I'm not an expert on Solr query parsing, but there *must* be a way to =
submit a query that is not turned into a phrase query.  Really. =20

And if you have configured an analyzer that includes a query-time =
filter, it should be invoked, regardless of whether a phrase query is =
constructed.
