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
