When Bruno said a "Core level handler", he meant a RequestHandler registered in solrconfig.xml and thus accessible as /solr/coreName/admin/encrypt as seen here: https://github.com/apache/solr-sandbox/blob/4e1819ff8a3758becca19bf337ecd1b352dba805/encryption/src/test/resources/configs/collection1/solrconfig.xml#L54 There is ambiguity of the idea of a core or even collection "admin" handler. Do we mean CoreAdminHandler (registered at node level), or do we mean any handler registered *in* the core that we characterize as being administrative in nature.
Some of our handlers like SearchHandler are aware of the collection and operate over the whole collection namespace. Most handlers (?) only know about the core it's registered in, yet can nonetheless be contacted via a core or collection request.
