Query N random challenges #212

Open tschaffter opened 3 years ago

tschaffter commented 3 years ago

Motivation

Display 1 or more random challenges (similar to Wikipedia random page). It would be nice if this could be as a sorting strategy.

Proposed solution

Use $sample provided by MongoDB.

Limitation:

The current implementation may return a document more than once?
It does not seem that $sample takes in a seed for the RNG. If it did, we could have used it to query a second and more pages of results.
