Requête imbriquée dans elasticsearch

Im avoir de problème pour faire une requête imbriquée de travail avec elasticsearch (Si je supprime l'un de la requête de chaînes qu'il fonctionne). le problème que j'essaye de résoudre, c'est que j'ai un document (Fermeture) contenant une liste de fermetures. Et je recherche une valeur dans la liste des fermetures d'où une autre valeur est de répondre par une condition. C'est seulement à prendre de la valeur à partir d'un lorsqu'il y a fermeture d'argan=1

{"query":{
  "bool":{
     "must":[
        {
           "nested":{
              "query":{
                 "query_string":{
                    "default_field": "closures.rating",
                    "query": "5"
                 },"query_string": {
                    "default_field": "closure.argang",
                    "query": "1"
                 } 
              },
              "path":"closures"
           }
       }
     ]
  }
}}

Im obtenir cette erreur-réponse;

Ma cartographie ressemble à ceci.
