Statistics/aggregated values per group in a grouped response
------------------------------------------------------------
Key: SOLR-2931
URL: https://issues.apache.org/jira/browse/SOLR-2931
Project: Solr
Issue Type: New Feature
Reporter: Morten Lied Johansen
We need to get minimum and maximum values for a field, within a group in a
grouped search-result.
I'll flesh out our use-case a little to make our needs clearer:
We have a number of documents, indexed with a price, date and a hotel. For each
hotel, there are a number of documents, each representing a price/date
combination. We then group our search result on hotel. We want to show the
minimum and maximum price for each hotel.
Other use-cases could be to calculate an average or a sum within a group.
We plan to work on this in the coming weeks, and will be supplying patches.
