Feature Request/Idea: Filter dataverses by number of datasets

[vera]

Overview of the Feature Request

Using the search API /api/search, I would like to filter dataverses by number of datasets.

What kind of user is the feature intended for?

API user

What inspired the request?

I'd like to find only dataverses that have content, e.g. filter by number of datasets > 0.

What existing behavior do you want changed?

Number of datasets in a dataverse should be added to the solr index so it can be used as a filter in the search API.

Any brand new behavior do you want to add to Dataverse?

no

Any open or closed issues related to this feature request?

no

We have a similar thing going on for datasets. You can get the number of files, like this:

curl -s https://dataverse.harvard.edu/api/search?q=dsPersistentId:%22doi:10.7910/DVN/TJCLKP%22 | jq . | grep fileCount

    "fileCount": 3,

Here's how we added it:

• in Search API show fileCount for datasets #6601 #6623
