sorting
it is somewhat related to faceting (https://github.com/castorini/covidex/issues/46) but requires much less work and thinking.
one of the feedbacks we have received directly from the feedback form is the need of sorting the result based on publication dates. i agree this is an important feature, especially since our index is updated weekly. what people want is more of differential.
can we add it quickly?

since we don't want to break re-ranking too much, how about "chronologically sort top-50"?
This is actually a much harder problem then it seems... and dates back more than ~20 years, at the dawn of web search. The problem back then was how to combine a static prior (say, PageRank or HITS) with a relevance score (e.g., BM25). Since both are continuous qualities, you've transformed a simple linear ranking problem into a multi-objective optimization problem - the two dimensions being relevance and page quality.
This is exactly the same situation here, substitute PageRank for time...
Can we do like google scholar, i.e., "since 2020", "since 2019" ..., "custom range"?
