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](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

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" : {}}}  
'
