Sorting and displaying item search results in collection with Person entity type

[pilasou]

When Person entities are used, searching a persons name in DSpace 7 present 2 major limits:

1. Sorting: no option exist to sort by name (the existing Title sorting option are not relevant for person item)
2. Information display: only names are displayed in search results which render disambiguation difficult.

In the following example, we conducted a simple search for "Bernier, Jean" as an expression and selected the Person value in the Item Type facet :

Results with “Most relevant sorting”

Improvments

1. A way to improve sorting would be to add an option Person Name (A to Z). This option should be provided only if entities are used (image below is illustrated the new name sorting).
   

2. Another way to improve results would be to add the person.affiliation.name metadata for each results, as illustrated below (as illustrated below)
