The implicit router is the only one you can use when you're doing time interval sharding, because it's the only one that allows the addition of new shards after collection creation. There is a reason that we are considering renaming the "implicit" router to "manual" instead. https://issues.apache.org/jira/browse/SOLR-6630 When you use the implicit router, you're completely in charge of sharding. There is no automation. You must name the shards, create them, delete them, and inform Solr during indexing about which shard will get new documents. If you want to only query a subset of the shards in a collection, you are responsible for telling Solr that with the shards parameter on the query. If you want to come up with a way to patch the Solr source code to add a new router that does automated time interval sharding, that will be welcome. Thanks, Shawn
