Automatic creation of indexes

[Jokin Cuadrado]

Hi, I'm using solr to store time series data, log events etc. Right now I
use a solr cloud collection and cleaning it deleting documents via queries,
but I would like to know what approaches are other people using.
Is there a way to  create a collection when receiving a post to a
inexistent inded? So i could use the date as part of the index name, and
the cleanup process would be just to delete the old collections.
