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
Does any one have solutions for this problem ?
