External Hard Drive search stopped working after MacBook update

Please help,I have been using DJPro for a while now on MacBook Pro, I have been able to search all files Spotify,itunes and my external hard drive via “search mac”, yesterday my Macbook recommended an upgrade/update to macOS High Sierra Version 10.13.1 which i did, now i cannot search my hard drive through the “search mac” box, the spotify and iTunes search still works though, i think the upgrade has affected this, can you help please, thanks Dave
