Spotlight not working on Mac

• Spotlight sometimes has trouble indexing after upgrade of Mac Os to El Capitan, which means it will only search a limited number of databases and will often bring up no answer for very common queries. The good news is this typically only happens once, while Apple restores the indexing process.

• If it keeps on underperforming, visit System Preferences, go to Spotlight, and look for indexing options under Search Results. Here you can see control what Spotlight is searching and what it isn’t. Make sure that the proper indexes are selected for your searching needs
