but what about these examples:
"elvis", "elvis presley" and "elvis presley suspicious minds".
what does it matter how fresh each answer is? its got absolutely nothing to do with it.
practically every single search term you can imagine for elvis, whether it is a two word term or longtail, derives no benefit from weighting in freshness.
the only time that freshness helps is when you're searching for some kind of elvis CD, book or TV programme -- something that you want to buy or watch.
