On Gmail some mails are not listed by search even if keyword is included. I search all messages based on the email. The global search listed only 3 messages even if I can find 5 emails in a directory (Gmail tag but in my case the folder has been created with Thunderbird). As an information Gmail build 3 discussions (same title) with 5 messages as in the same time Thunderbird show me only 3 messages then listed under list form. "5 on 5" are announced on the preview but only 3 listed on the list view ("Afficher les résultats sous forme de liste") My current release is 128.10.0esr (64 bits) on Windows 11.
