Realtime /get versus SearchHandler

[Benson Margulies]

A discussion over on the dev list led me to expect that the by-if
field retrievals in a SolrCloud query would come through the get
handler. In fact, I've seen them turn up in my search component in the
search handler that is configured with my custom QT. (I have a
'prepare' method that sets ShardParams.QT to my QT to get my
processing involved in the first of the two queries.) Did I overthink
this?
