Search doesn't work properly while typing initial text; works if I add an extra letter & delete it

I have a simple datatable with Bootstrap2 from the example.

When I enter a search for 'Cruz', and the table displays no results even though there is a name 'Cruz'. When I add any letter and then delete that letter, the table shows the record properly.

Does anyone know why this may be? Is it something I could change in my configuration to fix it so the initial search works the same way?

Thanks!

Here is my configuration:
