I'm using both the qb and the function, so the function gradually boost
fresher documents and the qb act as an extra boost for the most recent ones.
Good to now that it's interesting to avoid such precision, in fact I'm
rounding my times avoiding using NOW, so it's fine for me.

Thanks for the answer Chris. The DisMax query handler is just amazing!

i personally recommend the function approach, because it gives you a more
gradual falloff in terms of the scores of documents ...

I think in this case you can use a "bq" (Boost Query) so you can apply this
boost to the range you want.
your_date_field:[NOW/DAY-24HOURS TO NOW]^10.0
This example will boost your documents with date within the last 24h.

Try using a boost function (bf) parameter like this:
bf=recip(rord(listedDate),1,1000,1000)^2.5
This should boost documents with more recent listedDate so they appear
higher in the results list. For more info see the wiki page on
