How to have search keywords


I don’t know why I can’t see keywords on Matomo in my statistiques by default. I found this guide :
I follow all the steps but I have a problem here :"Login to Matomo as Super User, click on “Administration (cog icon)” on the top right, and click on “Search Performance” under “System”. "
I don’t have this menu?
I have only these item menu :

  • Paramètres généraux
  • Utilisateurs
  • Extensions
  • Géolocalisation
  • Messagerie Mobile

Can you help me please ?
