Improve Display Logic in Alma Uresolver to show all variant coverage statements in a collapsed menu
Ideally, Alma should be able to display ALL unique variant coverage statements when showing a collapsed menu.
If a library uses the Display Logic rules to for example show Proquest as an option only once in a services menu, this works very well where a journal may be in 12 Proquest databases with the same coverage.
However, when the coverage varies significantly between these databases, Alma uresolver will still just show one of the coverage statements and a user will only see a subset of holdings and believe this is all the library has. (eg Nursing standard in Proquest is a good example in some it is 1998-2013 and others is 2015 +, )
The most obvious case is when using the A-Z list or a general Primo search to find a journal title.
In SFX it is possible to add a year or source parameter to the display logic rule so that the collapse display logic only applies when the user specifies a date or when the open url does not come from the A-Z list. This means that a user wanting to use Primo or the A-Z to see ALL date holdings of a given serial title could see all possible links with their coverage statements, not just one statement per provider.
It would be better if the collapsed menu could be preserved and all the unique holding statements were shown, however, the SFX logic of conditionally showing all links is preferable to the current Alma behaviour.
