Search Box Combining two columns (Search Page) ASP.NET

[Nemphyst]

I am having some trouble in my search.aspx page (Search Page)

This is my code:

<asp:AccessDataSource runat="server" ID="AccessDataSource1" DataFile="_private/records.mdb" SelectCommand="SELECT * FROM [DriversRecords] WHERE ([LastName] LIKE '%' + ? + '%') OR ([FirstName] LIKE '%' + ? + '%')">
   <SelectParameters>
   <asp:formparameter FormField="LastName1" Name="FirstName" Type="String" />
   <asp:formparameter FormField="LastName1" Name="LastName" Type="String" />
   </SelectParameters>
</asp:AccessDataSource>

When I type the first name in text box...It's Working the same when i type the last name.

But when i'm trying to combine them such us I'm going to type in textbox : "George Santos" the result is "No data found"??

Combing two columns returns to null?? How to do it?
