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.
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).
