Apple Mail Search issue

To fix that issue.

1) Quit Mail.app

2) Stop, Clear, and Restart your Spotlight indexation. To do so : https://support.apple.com/HT201716 OR

• Open Terminal.app
• Stop and Flush Indexation
• sudo mdutil -i off -E /
• verify the status
• sudo mdutil -s /
• Restart it
• sudo mdutil -i on /
• verify the status again
• sudo mdutil -s /

3) Clear the Mail.app indexes. You will find some "Envelope Index*" files in your ~/Library/Mail/V7/MailData folder. Trash them and empty the Trash. (They will be rebuild after relaunching Mail.app, don't worry).

To do so:

• From the Finder > Goto Menu > Go to folder: "~/Library/Mail/V7/MailData".
• From the Terminal.app: "open ~/Library/Mail/V7/MailData" (then Enter)

Restart your Mac. Re-open Mail.app, and all we be fine again.

PS: You need all those steps, and in this order ;-)

• This solution is for the more experienced MAC-hackers. I am just a plain user and I need a quick patch from apple. I don't understand most of the commands e.g. "sudo mdutil -i off -E /" and I don't see why I should. Mac is marketed as the simple, user-friendly solution but...
• I am frustrated.
