Inventory. Result list Refined display rules MCL. Sort on primary contributor

Laura Daniels:
MM SMEs have expressed a desire, that is, to focus on the longer-term goals rather than interim goals if they can't be built on directly. The lack, for instance, of call number in the search results display of the holdings segment, would not be addressed by the improvements in the JIRA features listed below. So I agree with you, @charlotte, that putting resources toward the hierarchical display instead (UXPROD-491), if at all possible, is in our best interest.

This feature is split out of UXPROD-1634 - the library ranking is kept from the original feature, which previously included all relevant refinements of the result list for the MVP.

The cap.plan team has asked for getting the different improvements split into their own feature:

1. UXPROD-1634 (index title/title)
2. UXPROD-2667 (sort on contributor, when more than one contributor is listed)
3. UXPROD-2668 (Adding instance HRID)
4. UXPROD-2669 (Adding resource type)
5. UXPROD-2670 (Adding format)
6. UXPROD-2671 (Adding edition)
7. UXPROD-2703 (Adding publication date)

Overview: The result list has for the basic alpha implementation been: Resource title, and all listed contributors. With the refined use of elements implemented for beta, we need to configure the results in the Result list based on:

1. Display the primary contributor
2. If no primary contributor is displayed, then list the first three mentioned contributors, and sort on the fist listed one
3. If no contributors, the result will only be the Index title/Resource title, and publisher, etc.

Notes:
This is critical for the results list display to be useful for any searches, displaying the title data of the instance record.

Usecase:
As a librarian who is searching in Inventory.
I want the search results to display the primary contributor
If no primary contributor is displayed, then list the first three mentioned contributors, and sort on the fist listed one
If no contributors, the result will only be the Index title/Resource title, and publisher, etc.

Out of scope:
Future need: customizable results lists (tenant level and user level)
