      Description

      Hi,

      After trying without success to post my trouble on the mariadb-discuss mailing list, so I posted it here:
      https://alioth-lists.debian.net/pipermail/pkg-mysql-maint/2020-November/014430.html
      with one follow up here:
      https://alioth-lists.debian.net/pipermail/pkg-mysql-maint/2020-November/014445.html

      This is strange because the same query works fine both on MySQL 8.0.21 (Ubuntu) and MySQL 5.7.26 (Debian).

      I don't know how to start with this and I am not familiar with the EXPLAIN output.

      Thanks,
      Patrice
