nsify = Qa::LDF::NamespacedSearchService.new do |service|
  service.namespace      = 'http://example.com/ns/'
  service.parent_service = a_search_service_instance
end

# when
a_search_service_endpoint.search('moomin') # => { 'id' => 'blah' }

# then
nsify.search('moomin') # => { 'id' => 'http://example.com/ns/blah' }
