无法在Elasticsearch大容量索引上指定“routing”字段(routing_missing_exception)

Question

我在Elasticsearch批量更新查询中指定路由时遇到问题。我有一个需要路由的映射：

PUT my-index/_mapping
{
    "_routing": {
      "required": true,
    },
    "properties": {
      "my-property": { "type": "text" }
    }
}

我可以使用查询参数routing fine插入单个文档：

PUT my-index/_doc/my-id?routing=my-routing
{ "id": "my-id", "my-property": "Hi"... }

但是，当我批量更新时，我不确定如何指定路由字段。文件上说

POST my-index/_doc/_bulk
{"index":{"_index": "ch-search-domain", "_type": "_doc", "_id": "my-id" }}
{ "id": "my-id", "routing":"my-routing", "my-property": "Hi" }

另外，虽然显然不受支持（这里的答案是使用“批量时每个单独文档的路由字段”，就像我在上面尝试过的那样，但我在老版本中尝试了其他选项以防万一）

POST my-index/_doc/_bulk
{"index":{"_index": "ch-search-domain", "_type": "_doc", "_id": "my-id", "_routing": "my-routing" }}
{ "id": "my-id", "my-property": "Hi"... }

也会失败：

{“type”：“illegal_argument_exception”,“reason”：“操作/元数据行1包含未知参数[_routing]”}

Answer 1

POST my-index/_doc/_bulk
{"index":{"_index": "ch-search-domain", "_type": "_doc", "_id": "my-id", "routing": "my-routing" }}
{ "id": "my-id", "my-property": "Hi"... }
