ElasticSearch: Updating nested document in array -

given document

curl -xput 'localhost:9200/test/me/here' -d '{   "top" : [     { "searchkey" : "change"},     { "searchkey" : "keep"}   ] }' 

i need update query add new field sub-document searchkey equal change , keep other sub-document intact. expected result then:

{   "top" : [     { "searchkey" : "change", "newfield" : "newvalue"},     { "searchkey" : "keep"}   ] } 

running query selects inner document index works, not know inner order in advance , quite fragile anyways:

curl -xpost 'localhost:9200/test/me/here/_update' -d '{     "script" : "ctx._source.top[0].newfield = v",     "params" : {       "v" : "newvalue"     } }' 

is there way tell es add new field inner document matches condition? like:

curl -xpost 'localhost:9200/test/me/here/_update' -d '{     "script" : "ctx._source.top[ctx._source.top.searchkey == s].newfield = v",     "params" : {       "s" : "change",       "v" : "newvalue"     } }' 

or, better , save headache if eliminate array , transform document to:

{ "change" : {}, "keep" : {} } 

you can use update script. see example:

put test/data/3/ {    "source": [      {        "name": "a",        "count": 1      },      {        "name": "b",        "count": 2      },      {        "name": "c",        "count": 3      }    ] }  test/data/3  post test/data/3/_update {  "script": " (int = 0; < source.size(); i++) {boolean f = false;for (int j = 0; j < ctx._source.source.size(); j++) {if (ctx._source.source[j].name == source[i].name) {ctx._source.source[j].count = source[i].count;f=true;break;}}\nif(!f){ctx._source.source.add(source[i]);}}",  "params": {    "source": [      {        "name": "a",        "count": 10      },      {        "name": "b",        "count": 30      },      {        "name": "d",        "count": 50      }    ]  } }  test/data/3
