如何在 Postman 中发送 elasticsearch 多搜索请求？

Question

I'm trying to send elasticserach multi search request via postman as below:

POST - http://localhost:9200/_msearch
content-type : x-www-form-urlencoded
body:
{"index":"accounts"}
{"query":{"bool":{"should":[{"match":{"owner.first_name":"Creeple"}}]}}}

However, I'm getting following error:

{
  "error": {
    "root_cause": [
      {
        "type": "parse_exception",
        "reason": "Failed to derive xcontent"
      }
    ],
    "type": "parse_exception",
    "reason": "Failed to derive xcontent"
  },
  "status": 400
}

Note that if I perform same request via my play code, results are succesfully fetched.

WS.url("localhost:9200/_msearch").withHeaders("Content-type" -> "application/x-www-form-urlencoded").post(query)

Answer 1

Three things are important here:

1. When inserting body, select raw radiobutton and Text (or JSON) from dropdown.
2. Add header: Content-type: application/x-ndjson
3. Most important: put new line after the last line of your query

Body:

Header:

Curl version:

curl -X POST \
  http://127.0.0.1:9200/_msearch \
  -H 'cache-control: no-cache' \
  -H 'content-type: application/x-ndjson' \
  -d '{"index":"script","type":"test"}
{"query":{"match_all":{}}}
'

You can also make your request body be json format and change your Content-Type be application/json, please take a look as below

I have found error for "Expected [START_OBJECT] but found [null]" when I use _msearch API in elasticsearch.
