How to copy a Watson retrieve-and-rank solr collection on Bluemix

Question

We have a large Solr collection on Watson's Retrieve and Rank service that I need to copy to another collection. Is there any way to do this in Retrieve and Rank? I know Solr has backup and restore capability, but it uses the file system and I don't think I have access to that in Bluemix.

Answer 1

I'm not aware of any way to do this, beyond the brute force approach of just fetching every doc in the index and adding the contents to a different collection. (And even this would be limited to only letting you fetch the fields that you have stored in the first collection).
