Change which fields are "looked up" by a lookup field /relation

I have 2 custom Objects.

 

The first one is called Graduate, the Second is called Graduate Cases. 

I created a lookup field on Graduate Cases to lookup information on Graduate.  When I click the field on Graduate Cases and I type in data to be looked up.  The only Data I can look up is a field called Graduate Number, Which by default would be Graduate name, or "the record name"

 

Is there a way to specify what field the lookup field looks up?

 

As there can be numerous error in using this format. 

 

thanks,

Jon
