Subject Re: Bubbling up newer records

No default behavior of Lucene does this.

My approach is to create a time weight query with a scorer that weighs in
the time based on a user-defined formula. This way, you can view the
explained query with the time weighting information, and the weighting can
be dynamically controlled.

This is a built-in feature of DBSight and works well in real production
sites. I am not sure how payload can help. If payload is used to store date,
it seems redundant since you can easily store date field in the document,
and you can get the date from the field cache pretty quickly.
