i want to get a list of people that have more positions than 1 . this is an array.i've tried as below  
var searchResponse = client.Search(s =\> s.Type("person")  
.Query(q =\> q.Nested(n =\>  
n.Path(p =\> p.Positions)//  
.Query(qr =\> qr.Script(scr =\> scr.Source("doc['positions'].values.lenght \> 1")  
.Lang("painless"))))));

but it give me an error

I think the easiest way would be to store the length of the array as an additional field in the document. You can achieve this using the [script processor](https://www.elastic.co/guide/en/elasticsearch/reference/7.0/script-processor.html)
