Search problem after massive upgrade

Many occassions I found following error message after upgrade from very old version of Koha to the latest version. 

Software error:
Can't call method "branchname" on an undefined value at /usr/share/koha/lib/C4/Biblio.pm line 1570.

The solution is that execute a full index of Zebra. Apply following command;

sudo su
koha-rebuild-zebra -f -a -b -v library
