[Search] Aggregator returns result object

Browse Source 
The aggregator now returns a result object similar
to that of the providers, but the hits array contains
domain objects rather than searchResult objects.
Also removed overly complicated filterRepeats
function from the aggregator and replaced it with a
simpler one.
