Hi, Thanks Jacob and Ken for your replies. I am not able to change project architecture to add Lucandra even if it looks like a nice solution. Going the VIP way can definitely an option even if I'd be more keen to solve that "inside" Solr. I am thinking to try and play with Collection Distribution scripts or doing some custom stuff. But, please, if you have any other advice let me know. Thanks again. Tommaso
