Hi, There is nothing automatic that I know of that will create shards (or maybe you mean SolrCloud Collections?) every month. You can do that in your application, though, just create the Collection via the API. You can make use of aliases to have something like "last2months" alias point to your last 2 Collections. You would "shift" this alias every month after you create your new Collection. Of course, right after the shift, you would really be searching only 1 month's worth of data, so you may want to allow searching across last 3 Collections instead, optionally enforcing/limiting query to last 2 months based on document date and a range query.
