SearchBiblio.pm forked from SearchMarc.pm
opac-search-biblio.pl forked from opac-search.pl (just change module)
an attempt at a new search using FULLTEXT indexes.
NB: Boolean won't work without MySQL >v4.0
NNB: Will be slow without indexes added on Biblio table as follows:
ALTER TABLE biblio ADD FULLTEXT (author,title,unititle,seriestitle);
Only searching on "Any word" field just now.
more to come.
how it works :
* create the table marc_Tword with the following structure :
CREATE TABLE `marc_Tword` (
`word` varchar(80) NOT NULL default '',
`usedin` text NOT NULL,
`tagsubfield` varchar(4) NOT NULL default '',
PRIMARY KEY (`word`,`tagsubfield`)
) TYPE=MyISAM;
* open a console & type export PERL5LIB & export KOHA_CONF as usual.
* fill this table with misc/build_marc_Tword.pl. Warning, this script uses a very very consumming but very fast method to fill the table : it does everything in memory, then write everything. Another method is provided (& commented), but it's 100x times slower (really !)
* open opac-search.pl and replace use C4::SearchMarc; by use C4::SearchMarcTest; as the API hasn't changed, it will work immediatly.
* go to opac-search (advanced search) & search whatever you want. Should work fine.
LIMITS :
* build_marc_Tword has problem with extended chars (accented ones mainly). So don't be afraid if you get sql errors. They are not a problem for a POC
* search works always order by title, whatever you choose.
* search works only search WORDA and WOARDB, not yet WORDA or WORDB or WORDA except WORDB.
A sub had been forgotten to use the C4::Context->marcfromkohafield array, that caches DB datas.
this is only a little improvement for normal DB modif, but almost x2 the speed of bulkmarcimport... from 6records/seconds to more than 10.
if this parameter is defined, the url is used instead of the default one.
So, you can have your own stylesheet somewhere, and use it instead of the official Koha one.
* partial support of the "linkage" MARC feature : if you enter a "link" on a MARC subfield, the magnifying glass won't search on the field, but on the linked field. I agree it's a partial support. Will be improved, but I need to investigate MARC21 & UNIMARC diffs on this topic.

* added a button to cancel issue
* adding checkbox to cancel reserve on the book (checked by default)
* the cancelation reserve is done on reserves done for a given item or for any item
Nelsonville, pls test & confirm it's OK
In 2.4, a new DB structure will highly speed things and this limit will be removed.
FindDuplicate is activated again, the perf problems were due to this problem.
