How do I use the filter?

I am new to trying to figure this whole thing out, but I am trying to inventory our School District's computers into the Manage Engine software.  I want to try and do them one school at a time to get the hang of it, but when I go to the Assets > Workstations page, and click filter, I type in (like) VP* hoping to get results that only display computer names that start with "VP".  When I hit enter, it just takes me back to the default workstations page.  Is this correct?   Or am I approaching this completely wrong?
