Elasticsearch - index only part of the object -

is possible index part of object in elasticsearch?

example:

$ curl -xput 'http://localhost:9200/test/item/1' -d ' {     "record": {         "city": "london",         "contact": "some person name"     } }  $ curl -xput 'http://localhost:9200/test/item/2' -d ' {     "record": {         "city": "london",         "contact": { "phone": "some-phone-number", "name": "other person's name" }     } }  $ curl -xput 'http://localhost:9200/test/item/3' -d ' {     "record": {         "city": "oslo",         "headquarters": { "phone": "some-other-phone-number",                            "address": "some address" }     } } 

i want city name searchable, remaining part of object want leave unindexed , arbitrary. example fields can change it's type object object. possible write mapping allow such behaviour?

update

my final solution looks this:

{      "test": {         "dynamic": "false",         "properties": {             "name": {                 "type": "string"             }         }     } } 

i add "dynamic": "false" on lowest level of mapping , works expected.

you can achieve disabling dynamic mapping on entire type or inner object record:

"mappings": {     "doc": {         "properties": {             "record": {                 "type": "object",                 "properties": {                     "city": {"type": "string"}                 },                 "dynamic": false             }         }     } }
