One of my favorite applications on my Mac is Alfred. I use it all day every day, and it is impossible for me to believe that I have only posted once about it in all of DocumentSnapdom.

View the video below, or click here to watch it on YouTube. If you are able to, I recommend that you watch it with HD turned on.
This video on finding files with Alfred is part of a series of quick videos on paperless tips and topics. View more in the series here.
