> 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.
