It is easy to find the questions with the best scores and the worst scores.
But how can I find the answers with the best scores and the worst scores ? Is a ranking of the answers concerning the score available ?
This can be done via the search bar.
is:answer will let you search for only answers. Then you can sort by vote. You can even limit the results by
is:answer score:100 to get only answers whose score is $\geq100$. This can be filtered even more by adding
is:answer score:100 isaccepted:1 and focusing only on those answers which have been accepted, although your mileage may vary as far as "highest ranked" in that case.
Data Explorer (SEDE) is useful for tasks like this. (With the warning that the data in SEDE are updated only once a week, so the most recent posts are not in the database. And also some posts might have gained a few more upvotes or downvotes since the database was last updated.)
You can try something like:
I believe this answers the question satisfactorily. Still, I cannot resist to add a small remark. It is understandable that people might be interested in post with high score. (Since the upvotes the post gained means that many users saw there something worth upvoting.) On the other hand, it worth keeping in mind that looking only at such post might contribute to a kind of Matthew effect.
