I'm using Zend Lucene in a Symfony 2 project, via EWZSearchBundle. It's all working well, but now that the site has bedded in for a few months we're finding that some of the search results for some keywords, while perfectly accurate, aren't great.
As a first step, I'd like newer articles to be prioritised over older ones. Is there a way to do this with Luence (I can't find anything relevant in the docs, though I may have missed it), or should I do this as a layer above the Lucene search (i.e., loop through the hits and add a fudge factor to the scores based on the article age)?
