The challenge is to search for the inserted record with an inline SOSL search, using Execute Anonymous.

This is what I did using Execute Anonymous Window
 

List<List<sObject>> searchList = [FIND 'Mission Control' IN ALL FIELDS 
                                  RETURNING Contact(FirstName, LastName,
                                  Phone, Email, Description)];
Contact[] searchContacts = (Contact[])searchList[0];
System.debug('Found the following contacts:');
for (Contact c : searchContacts) {
   System.debug('"'+c.LastName + ', ' + c.FirstName+'"');
}

But still there's an error when I check the challenge.

Challenge Not yet complete... here's what's wrong: 
Could not find the contact's name in the debug log. Be sure to run a query for your record, and to write your contact's name to the debug log using the System.debug() method.
