> I would like that we support something like \{{FeatureField.newSaturationQuery}} but
that works with features that are computed dynamically like recency or geo-distance, and is
still optimized for top-hits collection. I'm starting with recency because it makes things
a bit easier even though I suspect that geo-distance might be a more common need.
