[Koha] Sorting search results - Zebra

[HEALEY, Sally]

Hi,

We are using Koha 16.11, and Zebra.  

We have individual records for different item types - e.g. hardback, paperback, DVD, large print, audiobook etc.  A search will return many records with equal ranking, which is correct, as they are all the same title.

When records are ranked equally, they are then sorted by bibilonumber in descending order, with the highest biblionumber (newest) displaying in the results first.  For example:

Result	Title	Type	Copies	Rank	Biblionumber
1	ABC	DVD	4	90%	44567
2	ABC	LP	2	90%	34689
3	ABC	PBK	63	90%	23456
4	ABC	HBK	80	90%	12345
5	CDE	DVD	11	64%	44235
6	CDE	HBK	43	64%	22132

We would like equally ranked records to be sorted by biblionumber ascending, so the oldest items are shown first.  This means our hardback/paperbacks would sit at the top of the search results, as these are purchased before multimedia and large print.

Result	Title	Type	Copies	Rank	Biblionumber
1	ABC	HBK	80	90%	12345
2	ABC	PBK	63	90%	23456
3	ABC	LP	2	90%	34689
4	ABC	DVD	4	90%	44567
5	CDE	HBK	43	64%	22132
6	CDE	DVD	11	64%	44235

Does anyone know if it's possible to achieve this, and how to do so?

Many thanks,

Sally
