Atlas Search on Non atlas Hosting?

Wondering if the full text search on Atlas will remain as Atlas platform only facility or is it planned or already possible to use the full text search API in privately hosted clusters on Open stack cloud ?

Thanks

Can you tell us more about your use case and your plans? We do not plan to offer Lucene on-premise at this time because of complexities associated with managing it. Is there a reason you require it on-premise?
