Hey,

you need to use one of the score functions mentioned in

So either script_score, boost factor, random or one of the decay
functions.. the error message is also telling you not to forget the query
field inside of the function score.

Hey I realize this is an old thread, but just in case anyone else has this
problem, it's almost definitely a versioning issue... updating to 0.90.10
solved it for me.

I think I got an older version by using brew install, but
download/installation directly from the website is super
easy: Elasticsearch Platform — Find real-time answers at scale | Elastic
