How to use multi search

Elastic Stack Elasticsearch
1

Hi,

I can not get how to use multi search API in elastic search.

I am creating following HttpGet request.

URL : http://localhost:9200/_msearch

Body of HttpGet Request

{"index" : "test"}
{"query" : {"match_all" : {}}, "from" : 0, "size" : 10}
{"index" : "test", "search_type" : "count"}
{"query" : {"match_all" : {}}}
{}
{"query" : {"match_all" : {}}}

{"query" : {"match_all" : {}}}
{"search_type" : "count"}
{"query" : {"match_all" : {}}}

After executing above request through REST client it's giving following
error.

{"error":"Failed to derive xcontent from
org.elasticsearch.common.bytes.BytesArray@0"}

I do not know what I am doing wrong? can somebody help me?

Thank you
Hemang

Hiya

{"index" : "test"}
{"query" : {"match_all" : {}}, "from" : 0, "size" : 10}
{"index" : "test", "search_type" : "count"}
{"query" : {"match_all" : {}}}
{}
{"query" : {"match_all" : {}}}

{"query" : {"match_all" : {}}}
{"search_type" : "count"}
{"query" : {"match_all" : {}}}

What are those blank lines doing there? And you're missing a {} before
the second last {"query" : {"match_all" : {}}}

This works for me:

curl -XGET localhost:9200/_msearch -d '
{"index" : "test"}
{"query" : {"match_all" : {}}, "from" : 0, "size" : 10}
{"index" : "test", "search_type" : "count"}
{"query" : {"match_all" : {}}}
{}
{"query" : {"match_all" : {}}}
{}
{"query" : {"match_all" : {}}}
{"search_type" : "count"}
{"query" : {"match_all" : {}}}
'
