You have to build your own Similarity for that.

Have a look at the FunctionQuery capabilities in Lucene in  
org.apache.lucene.search.function

You can use this to have field values factor into the score.

Hi All,
 I need help on retrieving results based on relevance + freshness. As of
now, i get based on either of the fields, either on relevance or freshness.

 how can i achieve this. Lucene retrieves results on relevance but also
fetches old results too. i need more relevant results with freshness too.

Regards,
Destin~ed

You want a bit less score the older the document is?

Search the archives for CustomScoreQuery and System.currentTimeMillis.

Here is something I found in the Google cache:
