部分更新文档而不删除Elasticsearch中的缺失字段

Question

假设我想索引文档

SQLitePCL

返回

PUT twitter/_doc/1
{
    "user" : "kimchy",
    "any" : "thing"
}
GET twitter/_doc/1

然后我想更新文件（没有完全覆盖原文件）[注意字段的差异]

{
  "_index": "twitter",
  "_type": "_doc",
  "_id": "1",
  "_version": 3,
  "found": true,
  "_source": {
    "user": "kimchy",
    "any": "thing"
  }
}

但是ES会覆盖整个文档。有没有办法让丢失的田地不受影响？

理想情况下，我想

PUT twitter/_doc/1
{
    "user" : "kimchy",
    "some" : "thing"
}
GET twitter/_doc/1

{
  "_index": "twitter",
  "_type": "_doc",
  "_id": "1",
  "_version": 6,
  "found": true,
  "_source": {
    "user": "kimchy",
    "some": "thing"
  }
}

谢谢！

是的，你需要做partial update，就像这样

POST twitter/_doc/1/_update
{
  "doc": {
    "user" : "kimchy",
    "some" : "thing"
  }
}
