title: How do I give more weight to newer articles in Sphinx search?
body: <p>I have a Sphinx search on a django site that is running very well. It finds excellent matches for all sorts of queries. I would like to be able to give a boost in ranking to newer results. Quite often articles that are many years old will rank higher than brand new articles. The older articles contain the search term more often, so have higher relevancy, but the new articles are still very relevant, so I would like them to appear first. </p>
  
  <p>I tried to read the Sphinx documentation about weighting, but it is incredibly confusing and filled with terminology that I don't really understand. I want to keep the search mostly the same as it is, I just want to give a slight boost in ranking to results with more recent pub_dates.</p>
