         any query time fq params the user may specify, as a mechanism for
         partitioning the index, independent of any user selected filtering
         that may also be desired (perhaps as a result of faceted searching).

         NOTE: there is *absolutely* nothing a client can do to prevent these
         "appends" values from being used, so don't use this mechanism
         unless you are sure you always want it.

    <!-- "invariants" are a way of letting the Solr maintainer lock down
         the options available to Solr clients.  Any params values
         specified here are used regardless of what values may be specified
         in either the query, the "defaults", or the "appends" params.

         In this example, the facet.field and facet.query params are fixed,
         limiting the facets clients can use.  Faceting is not turned on by
         default - but if the client does specify facet=true in the request,
         these are the only facets they will be able to see counts for;
         regardless of what other facet.field or facet.query params they
         may specify.

         NOTE: there is *absolutely* nothing a client can do to prevent these
         "invariants" values from being used, so don't use this mechanism
         unless you are sure you always want it.
