Subject using date-recency criteria within Lucene
Date Thu, 18 Jan 2007 22:00:02 GMT
We want to be able to apply a date-score criteria  within Lucene so that more-recent documents
score higher.
  We also want to be able to apply some boost factor to this date-field score.
  Right now we use Lucense to score the documents based on search citeria and then apply our
own "recency-of-date+bost factor factor" formula.   We thus generate a combined score which
we then use to display results that now incorporate the date criteria.
  But we prefer to do this completely within Lucene.   Is there a way to do this? What is
the best way? Which functiojn, field would we use?
  Thank you,
