Almost but not quite.  A query for www.edge.net will first search for
the string "www.edge.net" in much the same way a query for cheese will
cause a search for the string "cheese".  If that search fails, then it
starts to reduce, and when reducing, it isn't searching for an object
matching the key, it is looking for a *referral*.

So a failure in finding "www.edge.net" will not turn up a host record
for "edge.net", but would turn up a referral for "edge.net", if you
had one.

So if you want queries on "www.edge.net" to find a host, then you need
to either have a host object with the hostname "www.edge.net" or
modify the host schema to have an indexed attribute for CNAMEs and put
www.edge.net in that.

The behavior you are describing would lead to weird behavior, IMHO.
Like, I submit a query to your server for alsdkjfs.edge.net and get
back a host record for "edge.net".  That isn't what I was looking
for.

It *is* logging the exact phrase it is looking for.  At some point in
the search cycle it is looking for "Referral=edge.net" and that
translates to a search string of "30QWQXedge.net".

This silly "30QWQX" stuff goes away in the next server version, btw.
