Defaults to true. In most cases multiple indexes are better: Searching against smaller dataset is faster You are less limited in mapping structure. It is a collection of documents with similar characteristics - for Elasticsearch does not impose any strict limit to the number of indices or shards, but that does not mean that there are not practical limits. In this tutorial, How can I easily compress 140 indices (some of which are up to 100 GB)?
