Max score multi match query

[Divy_Garg]

Hi,

I am using multi match query of Elasticsearch. Need to understand what is the maximum _score that multi match query can have. Please help with this.

{
  "query": {
    "multi_match" : {
      "query":      "john wick",
      "type":       "best_fields",
      "fields":     [ "first_name", "last_name" ],
      "operator":   "and" 
    }
  }
}
