Tweak rank/relevance algorithm

Rank algorithm configurable by 'rank' element inside service. So far
only, attribute 'cluster' is recognized. If cluster="yes", multiple
records inside a cluster boosts higher than single records. This
is default behavior and existing behavior. cluster="no" takes the
average score of each record in a cluster.
