Looks up an order by order number.

Returns a reference-to-hash describing the order. The keys of
C<$order> are fields from the biblio, biblioitems, aqorders tables of the Koha database.

Searches for orders filtered by criteria.

C<$ordernumber> Finds matching orders or transferred orders by ordernumber.
C<$search> Finds orders matching %$search% in title, author, or isbn.
C<$owner> Finds order for the logged in user.
C<$pending> Finds pending orders. Ignores completed and cancelled orders.
C<$ordered> Finds orders to receive only (status 'ordered' or 'partial').


C<@results> is an array of references-to-hash with the keys are fields
from aqorders, biblio, biblioitems and aqbasket tables.

=head3 FillWithDefaultValues

FillWithDefaultValues( $marc_record, $params );

This will update the record with default value defined in the ACQ framework.
For all existing fields, if a default value exists and there are no subfield, it will be created.
If the field does not exist, it will be created too.

If the parameter only_mandatory => 1 is passed via $params, only the mandatory
defaults are being applied to the record.
