Reference numbers

Expectations:

• Users expect search to be able to locate works by their local and external identifiers eg Catalogue API IDs, Sierra IDs etc and for these to appear first in results

• Works that mention the reference number in other fields should come after the exact match

• Searches should be case-insensitive

• Users searching for an identifier and other input, should find works matching the identifier and input at the top of the results

• Note: We have instances where a user may have one alternative version of a reference number that has been referred to as something else, e.g. WMS 682 / MS 682 / MS.682. They are the same item.

Examples:

• L0029993

• SA/MED/L

• 727416i

• HALDANE/4/16/1/4

• MS PERSIAN 373

• V1234567

• V1234567 i1234567 aTrf569
