// This provider exists because due to legacy reasons, we need to install
// two plugins for two namespaces for CouchDB: one for "mct", and one for "".
// Because of this, we need to separate out the search provider from the object
// provider so we don't return two results for each found object.
// If the above namespace is ever resolved, we can fold this search provider
// back into the object provider.
