I'm trying to retrieve results from solr such that newer documents'
scores are boosted. From the solr wiki it states that I should use a
function query to influence the score but I'm a little confused on howto
use a function query.
Searching through the archives I found a suggestion of using the _val_:
hack in the standard query handler, but when i tried that with
recip(rord(date),1,1000,1000)^2
to just test it I got an error saying
org.apache.solr.core.SolrException: undefined field recip
Can someone explain the function queries a little clearer and if I would need
to use a different query handler?
