Changing the score of a document based on the value of a field

[Martin Davidsson]

The SolrRelevancyFAQ has a heading that's the same as my message's  
subject:

http://wiki.apache.org/solr/SolrRelevancyFAQ#head-f013f5f2811e3ed28b200f326dd686afa491be5e
There's a TODO on the wiki to provide an actual example. Does anybody  
happen to have an example handy that I could model my query after?  
Thank you
