[Samba] increase log verbosity to troubleshoot spotlight issues?

[Alex]

Hi,

I was wondering if there was a logging category for which I can increase
the verbosity for spotlight?
I am trying to set up Samba 4 with Gnome Tracker as the backend, and I
followed the Samba wiki (
https://wiki.samba.org/index.php/Spotlight_with_Gnome_Tracker_Backend ).
The tracker backend is working, but spotlight itself still isn't working on
workstations (trying to search on a shared folder makes the client search
the whole drive, causing an smbd thread to use 100% cpu while it searches,
instead of using the tracker index).

grep -Ri spotlight /var/log/samba/ doesn't bring back any results.

Thanks,

Peter
