Why the use of cursor=* changes the relevance of the first retrieved records?

While not using cursor=*, the first results are mostly relevant with the query.

Not using cursor: https://api.crossref.org/works?query=Albert+Einstein+Elektrodynamik+bewegter+K%C3%B6rper

But when I include the cursor parameter to download all the documents, the sort of the records seems to be something else different from the relevance with the query.

Using Cursor: https://api.crossref.org/works?query=Albert+Einstein+Elektrodynamik+bewegter+K%C3%B6rper&cursor=%2A&rows=100

From the point of view of users, even if I want to have access to all the results, it is surely expected to still have the results sorted by relevance.

It is possible to sort by relevance.
