Querying in Node.js

[hassaanalich296]

I am trying to query and manipulate results of Splunk searches using node. I am using the oneshotSearch however, as I understand it isn't a function hence, it doesn't return anything and therefore, I am unable to access the updated values my global variable that I manipulate within the function. The question then is, how do I access the variables results outside service.oneshotSearch

var Splunk_2 = [{"Verification Code" : '', "Verification Number" : ''}]

// Run a oneshot search that returns the job's results
service.oneshotSearch(
    searchQuery,
    searchParams,
    function query_result (err, results) {
        // Display the results
        var rawIndex = results.fields.indexOf("_raw");                            
        // Print out each result and the key-value pairs we want
        for (var i = 0; i < results.rows.length; i++) {
           Splunk_2.push({"Verification Code": JSON.parse(results.rows[i][rawIndex]).data.message_body,
                         "Verification Number": JSON.parse(results.rows[i][rawIndex]).data.phone
        });
      }                           
   }
);
