How do I install overdrive media console?

I have a Mac with OS 10.9.2. I followed the library instructions: 1. Create an Adobe ID; 2. Tap the App store ; tap the search bar in the top right corner and enter OverDrive Media Console; then tap the blue SEARCH  on the keyboard. THERE IS NO BLUE SEARCH ON THE KEYBOARD. I tried Enter, but the answer is "Your search found no results".
