Last name serach in caller field

[NeethuB]

In servicenow in the incident form there is a assigned_to field but when we search caller we can only search by his first name like "amal murali" we can search him by amal then the amal first name people is showing but i want to serach by the last name too.

This is the complete line I put in the attribute advanced view,  t includes that part:

ref_ac_columns=last_name,ref_auto_completer=AJAXTableCompleter,ref_ac_columns_search=true
