当文档不存在时，更新插入不会添加新的(ElasticSearch)

Question

我正在创建这样的新文档：

PUT test/_doc/1
{
"counter" : 1,
"tags" : "red"
}

现在我想更新或插入文档，无论它是否已经存在：

POST test/_update/2
{
"script" : {
"source": "ctx._source.counter += params.count",
"lang": "painless",
"params" : {
"count" : 4
}
},
"upsert" : {
"counter" : 1
}
}

在我的情况下，_doc=2不存在，为此，我将upsert添加到查询中，以便在_doc不存在时自动创建它。

相反，我得到了这个错误消息：

{
"error": {
"root_cause": [
{
"type": "invalid_type_name_exception",
"reason": "Document mapping type name can't start with '_', found: [_update]"
}
],
"type": "invalid_type_name_exception",
"reason": "Document mapping type name can't start with '_', found: [_update]"
},
"status": 400
}

我是不是误解了它的工作原理？

更新

映射：

PUT /test
{
"mappings": {
"type_name": {
"properties": {
"counter" : { "type" : "integer" },
"tags": { "type" : "text" }
}}},
"settings": {
"number_of_shards": 1
}
}

尝试这个

您正在查看7.x文档这是您版本的文档：https://www.elastic.co/guide/en/elasticsearch/reference/6.8/docs-update.html

POST test/type_name/2/_update
{
"script" : {
"source": "ctx._source.counter += params.count",
