Answer 1

Please change the enclosing quotes from ' to " also escape the quotation marks " used inside the parameters as below and run the curl command :

curl -XGET gitlab.server:9200/ -H "Content-Type: application/json" -d "{\"query\": {\"simple_query_string\" : {\"fields\" : [\"content\"], \"query\" : \"foo bar -baz\"}}}"

An alternative is also available to put the json into a file, and use the @ prefix for the parameters.

json.txt

{
  "query": {
    "simple_query_string" : { 
      "fields" : ["content"], 
      "query" : "foo bar -baz"
    }
  }
}

After doing that run the curl command as below:

curl -XGET gitlab.server:9200/ -H "Content-Type: application/json" -d @json.txt
