$tags,$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 $extratables
|
|
|
|
optional argument containing extra tables to search. Used in conjunction with $sqlstring. See usage in opac-search.pl.
|
|
String... so ',items,issues,reserves' allows the items, issues and reserves tables to be used.in a where.
|
|
|
|
=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.
