Answer 1

To add a new element to your nested field you can proceed like this:

$ curl -XPOST 'localhost:9200/index/type/1212/_update?pretty' -d '
{
    "script" : "ctx._source.list_data += newElement",
    "params": {
        "newElement": {
           "list_id" : 121,
           "timestamp" : 1469050965
        }
    }
}'

To remove an existing element from your nested field list, you can proceed like this:

$ curl -XPOST 'localhost:9200/index/type/1212/_update?pretty' -d '
{
    "script" : "ctx._source.list_data.removeAll{it.list_id == remove_id}",
    "params": {
        "remove_id" : 122
    }
}'
