How to send elasticsearch multi search request in Postman?

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":{}}} '
