Well, you could always index the year/month/day separately. The query might be a bit slower and more cumbersome, but it is doable. And for indexing, you can probably use index-time transformers/components to split the date into the parts behind the scenes.
The usual other option is to use Date Math, but I don't think it fits your requirements. http://lucene.apache.org/solr/api-4_0_0-BETA/org/apache/solr/util/DateMathParser.html Regards, Alex.
