I'm setting up a search collection of news articles and want to return results by score, except that it would be good to change the weighting to score newer articles higher. News from 5 years ago may not be as relevant as news from last week or last month. I'm guessing there is nothing built-in for this. So I can look into weighting the score. But I was wondering if there is any good logic for doing this?
One thought was to round off the scores to the nearest integer, and then sort by score + date. This would bump newer stories that have similar scores. Or just bump the score a certain amount based on how new it is? It may just need trial & error, but suggestions would be welcome.
