[Koha] Cannot search Authority

[Piotr Kowalski]

I have just installed Koha 3.2.9 from Debian package Koha-common and now
trying it.
Authorities searching doesn't work in any context, the result is always: no
results found.
Explanation:
- authorities records (Person Name) were added manually and saved; are
visible in the database table auth_header
- rebuild_zebra script were triggered manually with parameters: -a -v
(verbose mode); it works well with no errors, always inserts or updates the
adequate number of records
- bibliographic records are searchable in a normal way 

Any help is welcome.

Best regards,
