如何为application.countries和application.countries.short_name

获取空数组和美国的结果？

Answer 1

简而言之，您希望获取包含美国或不包含任何国家/地区名称的结果。您可以在should之间而不是term

之间应用exists

{
"query": {
  "bool": {
     "should": [
        {
           "bool": {
              "must_not": {
                 "exists": {
                    "field": "application.countries.short_name"
                 }
              }
           }
        },
        {
           "term": {
              "application.countries.short_name": [
                 "US"
              ]
           }
        }
     ]
   }
 }
