Could you not index mmdd, and yyyy separately? First do
a match on mmdd to get all persons (this is also the set
of all 1-year matches), and then use yyyy to get 5-year,
and 10 year matches.

P.S. If you want to do a modulus, please see function
queries: http://wiki.apache.org/solr/FunctionQuery
Not completely sure, but in Solr 3.1, mod() should
be available from java.util.Math
