ES sort in server end when given fileds are equal

[Tomo_M (Tomohiro Mitani)]

random_score for function score query 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.

Random function in 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.
