Hello, I have a couple of questions related to this same topic, as far as I see the endpoint /api/discover/search allows the results to be sorted by:
score dc.title dc.date.issued dc.date.accessioned For example: /api/discover/search/objects?sort=score Would it be possible to sort them by the date of the last modification? I have tried something like the following, but it didn't work for me: /api/discover/search/objects?sort=query:lastModified /api/discover/search/objects?sort=lastModified /api/discover/search/objects?sort=query Finally, what does the option to sort by "score" refer to, i.e., does it have any relation to item statistics such as number of downloads or something like that that determines their score?
