Entirely possible. Yet, this is what Apple presented in 2014: Jessica Mallet from Apple, Inc. gave a presentation on how Apple uses SolrCloud. She briefly outlined some terms and concepts and then dug into how Apple built a multi-tenant search platform with each cluster holding around one million logical indexes.
