I am quite surprised you need to do that since you say you installed from
Debian packages. All the installations I have done through the Debian
packages always have the zebra incremental indexing properly set in cron
and it is usually set to run every 5 minutes.
Quite apart from running it as root (and if it's automated, no need for the
-v), the normal cron job is *incremental* (-z) and this user is running a
*rebuild* (-r) every morning, which is absolutely necessary if any
cataloguers have deleted a biblio, overwritten a "fast add" with a Z39.50,
changed the 001/003 combination, etc etc.
We only run ./bin/migration_tools/rebuild_zebra.pl -b -r -v -x and (less
frequently) ./bin/migration_tools/rebuild_zebra.pl -a -r -v manually and at
the request of our cataloguers. If we've got a couple of conscientious ones
playing catch-up on older biblios imported from spreadsheets or fast-adds,
this can be as often as every 20 minutes (but it's trivial to do.) One of
my "to do" jobs is to incorporate a script into the staff-admin page so
that certain (senior) cataloguers can run this without calling me.
The cataloguers cannot work without it -- we insist that every "entry" is
verified in the OPAC at the time of cataloguing to ensure that what our
users see is what the cataloguers intended. Hence the need to run -r fairly
promptly. The search function down-time, while zebra is "cleaning", is only
a couple of seconds, particularly if you clean the logs, sessions, imports
and zebraqueue every 24 hours.
