select matching objects from array in elasticsearch -

- 

{     class: 1,     users: [{         name: 'abc',         surname: 'def'     }, {         name: 'xyz',         surname: 'wef'     }, {         name: 'abc',         surname: 'pqr'     }] }

i have document structure above object , want return users have name 'abc' problem matches name 'abc' returns array. want matched users .

mapping - 

{         "class":"string",         "users" : {             "type" : "nested",             "properties": {                 "name" : {"type": "string" },                 "surname"  : {"type": "string" }             }         }     }

then if have users field mapped nested type, it's start!

using nested inner_hits, can retrieve matching user names query one:

{   "_source": false,   "query": {     "nested": {       "path": "users",       "inner_hits": {        <---- magic happens         "_source": [           "name"         ]       },       "query": {         "bool": {           "must": [             {               "term": {                 "users.name": "abc"               }             }           ]         }       }     }   } }
