-
-A COPY of official SearchMarc, with some tests for inverted index table
-works only with 1 MARC tag/subfield

-$tags,$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 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.
