I believe you can use a function query to do this:
http://wiki.apache.org/solr/FunctionQuery
if you embed the following in your query, you should get a boost for more
recent date values:
_val_:ord(dateField)
Where dateField is the field name of the date you want to use.

Hi.
I am interested in a very similar topic like yours. I want to modify the
field named score and the document boost but not reindex the all fields
since it would take to much power.
Please let me know if you find a solution to this.
Kindly
//Marcus
