Update of /cvsroot/koha/koha/C4
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv15229/C4
Added Files:
SearchBiblio.pm
Log Message:
two new files
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.

C4::Search - Functions for searching the Koha MARC catalog
=head1 FUNCTIONS
This module provides the searching facilities for the Koha MARC catalog

=head1 findsuggestion($dbh,$values);
=head2 $dbh is a link to the DB handler.
use C4::Context;
my $dbh =C4::Context->dbh;
=head2 $values is a word
Searches words with the same soundex, ordered by frequency of use.
Useful to suggest other searches to the users.

=head1 findseealso($dbh,$fields);
=head2 $dbh is a link to the DB handler.
use C4::Context;
my $dbh =C4::Context->dbh;
=head2 $fields is a reference to the fields array
This function modify the @$fields array and add related fields to search on.

=head1 my ($count, @results) = catalogsearch($dbh, $tags, $and_or, $excluding, $operator, $value, $offset,$length,$orderby,$sqlstring);
=head2 $dbh is a link to the DB handler.
use C4::Context;
my $dbh =C4::Context->dbh;
$tags,$and_or, $excluding, $operator, $value are references to array
=head2 $tags
contains the list of tags+subfields (for example : $@tags[0] = '200a')
A field can be a list of fields : '200f','700a','700b','701a','701b'
Example
=head2 $and_or
contains a list of strings containing and or or. The 1st value is useless.
=head2 $excluding
contains 0 or 1. If 1, then the request is negated.
=head2 $operator
contains contains,=,start,>,>=,<,<= the = and start work on the complete subfield. The contains operator works on every word in the subfield.
examples :
contains home, search home anywhere.
= home, search a string being home.
=head2 $value
contains the value to search
If it contains a * or a %, then the search is partial.
=head2 $offset and $length
returns $length results, beginning at $offset
=head2 $orderby
define the field used to order the request. Any field in the biblio/biblioitem tables can be used. DESC is possible too
(for example title, title DESC,...)
=head2 $sqlstring
optional argument containing an sql string to be used in the 'where' statement. see usage in opac-search.pl.
=head2 RETURNS
returns an array containing hashes. The hash contains all biblio & biblioitems fields and a reference to an item hash. The "item hash contains one line for each callnumber & the number of items related to the callnumber.
=cut
=head2 my $marcnotesarray = &getMARCnotes($dbh,$bibid,$marcflavour);
Returns a reference to an array containing all the notes stored in the MARC database for the given bibid.
$marcflavour ("MARC21" or "UNIMARC") determines which tags are used for retrieving subjects.
=head2 my $marcsubjctsarray = &getMARCsubjects($dbh,$bibid,$marcflavour);
Returns a reference to an array containing all the subjects stored in the MARC database for the given bibid.
$marcflavour ("MARC21" or "UNIMARC") determines which tags are used for retrieving subjects.
