Hello, If I understand correctly,
1) to get the number of matches per price intervals in Solr, here are the different ways one can use: * per static price intervals: * facet.range * facet.query * per dynamic price intervals * there is Solr JIRA to get dynamic facet intervals: Solr JIRA 1581: Facet by function https://issues.apache.org/jira/browse/SOLR-1581 2) To get only price min and price max on a specific field for the whole index: * StatsComponent 3) Now my question is: I can get result grouping work OK with Solr 3.3, but how to get price min and max on each group (&group=true). Is there a Solr JIRA associated with it ? Lucene JIRA 3097: Post group faceting does https://issues.apache.org/jira/browse/LUCENE-3097 presents results in global facets and not in "per group" results. Thank you.
