I'm not sure if my answer would help you :-). Usually we do not need to know the min and max prices that our current database or solr is holding for all the products. Even if you were to that, would be complex and just make your business logic bigger and tedious.
Instead, we would know what is the min price and what would be the max price. Based on this you could create price buckets in solr using http://wiki.apache.org/solr/SimpleFacetParameters#Facet_by_Range In others words, Lets say my site is about selling cars, I would mention min price could be =0 and max price = 4000000 (4million just logical value) could be more than that. So price range will fall between those two logically defined fields. Based on that you could construct solr facet query range, that Solr will automatically give you the price range (price bucket what amazon calls it). Hope that is helpful :-). -- View this message in context: http://lucene.472066.n3.nabble.com/get-min-max-prices-as-facets-tp4099501p4099523.html Sent from the Solr - User mailing list archive at Nabble.com.
