[Koha] no result for search books

[Repke de Vries]

dear Nicole,  dear Zahid

(my remarks also relate to "how to run zebra deamon" from earlier  
today where Nicole added the same advice):

with an ordinary Koha installation everything is set but as per  
Nicole's advice needs the rebuild-zebra (see the FAQ she points to)  
on a regular basis to bring the wheels in motion.
What rebuild-zebra does is taking a copy of  all the new or changed  
bibliographic or authority records in your Koha database and have  
them indexed by Zebra for searching. The moment the index is done,  
you can search.  Rebuild-zebra also checks if records were deleted  
and removes them from the index.

HOWEVER: there must be a mistake in the FAQ because the parameter -r  
is *not* correct for hourly or every minute automatic running (this  
is what a cronjob does) of rebuild-zebra.
It should be -z.   And -a is for re-indexing authority records and -b  
for the biblio records. So: -a -b -z
This is what happens with -z: rebuild-zebra *first* checks in a  
special table in your Koha database (called: zebraqueque) which  
records were added, changed or deleted and then only copies / notices  
these and re-indexes.
This is what happens with -r:  the index is "reset" and *all* your  
records are copied from the Koha database for building a complete new  
index: could be thousands and thousands of them.
Imagine you start this "-r"  from scratch every minute in an  
automated way:  bad news for your Koha performance.

Correct me if I am wrong but this what we found out the hard way.

Yours, Repke de Vries
