User List Search - How To

I have created a list with two searchable fields - First Name and Last Name.
What I need is that both fields must be inputted before a user can submit a search, not just First Name for instance, but both First Name and Last Name must be filled before the submit button can be activated.

Is this possible?

Nope - there is no way to force people to populate a search field.
