更新Elasticsearch文档

问题描述：

此代码可以正常工作.但是，我不想将第三个国家/地区添加为另一个文档，而是要更新第一个文档.

This code is working as expected. But instead of adding the third country as another document, I want to update the first document.

DELETE /test_index

PUT /test_index

PUT /test_index/doc/1
{
   "parent": [
      {
         "name": "India",
         "label": "IN"
      },
      {
         "name": "China",
         "label": "CN"
      }
   ]
}

PUT /test_index/doc/2
{
   "parent": [
      {
         "name": "Pakistan",
         "label": "PK"
      }
   ]
}

因此，文档ID 1将有3个国家:印度，中国和巴基斯坦.我想我需要使用doc_as_upsert参数更新API.但是我不确定如何编写JSON.

So that the Document ID 1 will have 3 countries India, China and Pakistan. I guess I need update API with doc_as_upsert parameter. But I am not sure how to write the JSON.

答

您可以使用

更新

如果要在批量查询中使用它，也可以

If you want to use this in a bulk query, it is also possible

curl -XPOST 'localhost:9200/test_index/doc/_bulk' -d '
{ "update" : { "_id" : "1"} }
{ "script" : { "inline": "ctx._source.parent += ['name': name, 'label': label]", "lang" : "groovy", "params" : {"name" : "Pakistan", "label": "PK"}}}
'
