http://wiki.apache.org/solr/StatsComponent can give you min and max values.
Since it calculates additional statistics, i am not sure which one is faster: fetching min
and max separately or using stats component.

q=query&start=0&rows=1&fl=date&sort=date asc
q=query&start=0&rows=1&fl=date&sort=date desc
