Function Queries [1] can do that: - Using the values in Fields as factors in scoring. Also if you want to multiply it with the relevancy score, rather than add it, you can use boost query parser [2] [1]http://wiki.apache.org/solr/FunctionQuery [2]http://lucene.apache.org/solr/api/org/apache/solr/search/BoostQParserPlugin.html
