Hi, How about trying grouping with paging? First you do group=true&group.field=advertiserId&group.limit=1&group.offset=0&group.main=true&sort=something&group.sort=how-much-paid desc
That gives you one listing per advertiser, sorted the way you like. Then to grab the next batch of ads, you go group.offset=1 etc etc. -- Jan Høydahl, search solution architect Cominvent AS - www.cominvent.com Solr Training - www.solrtraining.com On 26. apr. 2012, at 08:10, solr user wrote: > Hi, > > We are planning to move the search of one of our listing based portal to > solr/lucene search server from sphinx search server.
