elasticsearch 更新时返回文档

Question

I need to get the updated document after update operation.

Using elasticsearch version 7.0.0 .

I tried:

curl -XPOST 'localhost:9200/dmf_product_match/_doc/YKsu3m0BxrmuyWilMQ-I/_update?fields=_source' -d '{
    "doc" : {
        "name" : "new_name"
    }
}'

But get this error.

{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"request [/dmf_product_match/_doc/YKsu3m0BxrmuyWilMQ-I/_update] contains unrecognized parameter: [fields]"}],"type":"illegal_argument_exception","reason":"request [/dmf_product_match/_doc/YKsu3m0BxrmuyWilMQ-I/_update] contains unrecognized parameter: [fields]"},"status":400}

Answer 1

Try

curl -XPOST 'localhost:9200/dmf_product_match/_update/YKsu3m0BxrmuyWilMQ-I?_source' -d '{
    "doc" : {
        "name" : "new_name"
    }
}'

You could also use "doc_as_upsert": true . Reference: this
