Hello @jhendr15. Thanks for posting in the Spotify Community!
I've occasionally had this happen to myself before too, but usually fix it by rebooting my phone or reinstalling the Spotify mobile app. If a reboot doesn't fix it for you, let me know if a reinstall of the app gets you anywhere. 🙂
Thanks for letting me know the device you're using and the version of Android you're on. You should also let us know whether you're on Spotify Free or Premium in your next reply, as well as the exact Spotify app version you're using. This can be found by tapping on Your Library > Settings Gear (top right corner) and scrolling to the bottom.
Performing a clean install usually resolves most issues on the Spotify mobile app for Android for a lot of people, myself included. If it does not fix your blank search issue, let me know and I'll rope in a more knowledgeable Rock Star or Moderator to help out. 🙂
