I want to make aggregations over inserted in Elasticsearch data but it means that inserted data should be consistent for all shards. Can I ensure consistency of inserted data or to know that data that was stored in ES become consistent? I don't need to make aggregations just after insertion and can wait for few minutes.

A **refresh** returns (successfully) once all previously-written data is exposed on all shards. You can either do this [explicitly as a separate step](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-refresh.html) or else [include it with the indexing operation itself](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-refresh.html).
