Obnavljanje zapisa u indexu

Za to bi trebao služiti Zebraqueue Daemon, ali ne radi kako treba (koha-zebraqueue-ctl.sh). Umjesto toga index se rebuilda svako malo uz pomoć crona

Pokrenuti kao user koha.

Dijakritički znakovi

Situacija: u bazu su povučeni zapisi iz NSK (Voyager) u kojima su naša slova s dijaktiticima zabilježena kao dva znaka (slovo bez dijakritika + dijaktitik).

Nije lijepo da takvi znakovi završe u Koha bazi, ali kad su već unutra, treba ih nekako učiniti pretraživima.
U datoteku /etc/koha/zebradb/etc/word-phrase-utf.chr dodati ekvivalente:

git

# Characters to be considered equivalent for searching purposes
equivalent č(cˇ)
equivalent Č(Cˇ)
equivalent ć(c´)
equivalent Ć(C´)
equivalent š(sˇ)
equivalent Š(Sˇ)
equivalent ž(zˇ)
equivalent Ž(Zˇ)

Sad to dobro radi kad se pretražuje s "normalnim" znakovima. Ostaje problem kod browsanja preko liknova - strgani zapisi nađu samo strgane (pr. http://10.60.0.253/cgi-bin/koha/opac-detail.pl?biblionumber=241488, Pavao Pavličić).

Zebra register i shadow

Veličinu zebra register i shadow treba podesiti sukladno veličini baze. Za oko 120.000 zapisa, dovoljno je 4G. Za FF je sada podešeno 16GB.

Z39.50 server

Dokumentacija

• http://koha.org/documentation/manual/3.0/administration/additional-parameters/z39.50-servers
• http://lists.indexdata.dk/pipermail/zebralist/2009-March/002142.html
• http://bugs.rot13.org/rt/Ticket/Display.html?id=377

Ali sve je uzalud jer je pravi odgovor na http://www.indexdata.com/zebra/doc/zebrasrv.html

The first two servers, "server1" and "server2", can be reached by both listener addresses - since no listenref attribute is specified.

Problemi

Neki zapisi nestaju u katalogu

Nepoznat obrazac u zapisima koji fale.

Nagađanje 1:

da li su problematični oni zapisi koji imaju različit biblionumber i biblioitemnumber?
To je dozvoljena kombinacija, ne bi trebalo smetati.
Problem je u nečem drugom, no ipak smo odlučili te zapise poindeksirati ponovo, ovako:

mysql> create temporary table foo as select max(id) as id from zebraqueue join biblioitems on biblioitems.biblionumber=zebraqueue.biblio_auth_number and biblionumber <> biblioitemnumber group by biblio_auth_number ;
mysql> update zebraqueue set done = 0 where id in (select id from foo) ;

Nakon toga pokrenuti rebuild_zebra.pl.

I dalje postoje zapisi koji se ne vide u katalogu.

Ovo javi kad se poindeksiraju svi zapisi s rebuild_zebra.pl -b -v -r:

00:24:15-02/02 zebraidx(1490) [log] Records: 238000 i/u/d 238000/0/0

Nagađanje 2:

Potrgan MARC

• napraviti dump MARC zapisa iz Kohe (uz pomoć WebPAC2)
• provjeriti s marclint
