Hello, I'm trying to boost results based on date using the first example here:http://wiki.apache.org/solr/SolrRelevancyFAQ#How_can_I_boost_the_score_of_newer_documents
However, I'm getting an error that reads, "Can't use ms() function on non-numeric legacy date field"
The date field uses solr.DateField . What am I doing wrong? Thank you! Daniel Higginbotham
