Indeed's Austin office has a DNS performance problem which we tracked
down to a database search efficiency problem. The issue is
SCOPE_ONELEVEL is used on wildcard dns searches, but onelevel searches
currently have a performance problem related to GUID indexing, so this
patch changes the search scope to SCOPE_SUBTREE.
