Elasticsearch- how to do multi search request on Sense or Head plugin

Question

I am trying to achieve this multi search request on sense and plugin head but I am not able to get what could be the problem? sample on doc is for curl, I cant comprehend what is the exact difference.

POST _msearch?pretty=1 
{"myIndex":"Product"}
{
  "fields": [
      "id",
    "Name"
  ], 
"query": {
 "bool": {
      "should": [
        {
          "query_string": {
            "default_field": "_all",
            "query": "key"
          }
        }
      ] 
    }      

  }
,
  "from": 0,
  "size": 5,
  "sort": [],
  "aggs": {}
}
{"myIndex":"Printer"}{
  "fields": [
      "id",
    "Name"  
  ], 
"query": {
 "bool": { 
      "must": [{
      "has_child": {
     "type": "Printer",
     "query": {
        "match": {
        "Name": "key"
        }
      }
    }
      }]
    }      

  }
,
  "from": 0,
  "size": 5,
  "sort": [],
  "aggs": {}
}

I am getting this error on sense. { "error": "JsonParseException[Unexpected end-of-input: expected close marker for OBJECT (from [Source: [B@48acbc4c; line: 1, column: 0])\\n at [Source: [B@48acbc4c; line: 1, column: 3]]", "status": 500 }

Answer 1

This is because of extra spaces. I got this error removed by removing extra space and next lines. In sense Run ctrl+I twice to first indent and then un-indent the query.

Hope this will remove the error.
