[`random_score` for function score query](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-function-score-query.html#function-random) is enough for you? It returns random score based on internal Lucene doc ids as a source of randomness, which is renumbered by merges.

If you want differente results even for repeated same query, maybe you have to use some script field with painless.

> Hello, What is the way to genereate a random value in Painless? Being able to draw one value from a set would be particularly great - I want to use it to add a new field to my mock data and I need a possibility to add one of the statuses ('Working', 'Archived', 'InReview') to my documents at random.
