rwxr-xr-x 3 elasticsearch elasticsearch 4096 Jan  4 16:08 ..
-rwxrwxrwx 1 root          root           145 Jan  7 11:57 session-duration-script.groovy
-rwx------ 1 root          root           124 Jan  7 12:52 calc-session-duration-script.groovy

Do I need to enable the groovy scripting for running the script_field query. From documentation I understand that ES cause execute scripts placed under /config/scripts with out enabling the scripting

You just need to wrap the definition of your script field within a script section, like this:

  "script_fields": {
    "my_field": {
      "script": {                 <---- add this
        "file": "my_script",
        "params": {
          "my_var": 2
        }
      }
    }
  }

Also make sure to enable dynamic scripting from stored script files in your elasticsearch.yml configuration file (+restart your node):

script.file: on

I just added "script": { line and it worked :) Thanks for the quick response !!!. Have another question . When i added "script_fields": { section the query the results returned only the field mentioned in the script_filelds section. Is there a way return all the fields in the document + script_fields – Karthikeyan Ramasamy Jan 07 '16 at 22:03
