Yes, definitely. If you abandon SolrCloud, then you gain some features that we call "LotsOfCores", and the number of indexes you have is not so relevant for performance. There may be a short delay when a user connects and tries to access their search, while Solr spins the core back up. I have no way to estimate how long that delay would be. https://wiki.apache.org/solr/LotsOfCores As Alexandre mentions, there is a little bit of terminology confusion, because cores will sometimes be referred to as collections, especially by those who are not as familiar with internal terminology used by the project. Until recently, the first core encountered by a new user, originating before SolrCloud was available, was named "collection1". This did not help with the confusion. Thanks, Shawn
