Thanks all ,  the problem is solved .  I don't know how .  I'm guessing it's an administrative issue

You probably need to rebuild the Search Index.  You can follow those instructions if you're hosting your own version, or if you're a Cloud customer you can contact Atlassian support and they'll do it for you.
