@ekraffmiller all changes addressed, thanks for the review!

@g-saracca I realized there is one more change needed, there is a sort type "Relevance" used when the CollectionSearchCriteria contains search text. For the API, sort=score. For example:

I'm going to put the PR back to InReview, sorry about that.

Hi @ekraffmiller , in the api endpoint docs there is nothing about sort by relevance, there is show_relevance but it's for something different. Sort can be date or name and Order asc or desc, but nothing about relevance.
Perhaps we need to extend the api endpoint to achieve that but maybe we can continue without that and do it in another issue after the api extension is done.

Ah ok, so when the user chooses sort by relevance, that is the same as doing a text search without a sort option. Makes sense, I don't think we need to update the API, I was just confused by the url params in the frontend.

Right, when you search something the url looks like this:
https://beta.dataverse.org/dataverse/root/?q=foo
And when clicking Sort By Releveance the url turns to this:
https://beta.dataverse.org/dataverse/root?q=foo&types=dataverses%3Adatasets%3Afiles&page=1&sort=score&order=desc
