Hi, I am trying to plot a non date field by time in order to draw an histogram showing its evolution during the week.
For example, if I have a tweet index: Tweet: date retweetCount 3 tweets indexed: Tweet | Date | Retweet A 01/01 100 B 01/01 100 C 01/02 100 If I want to plot the number of tweets by day: easy with a date range facet: Day 1: 2 Day 2: 1 But now counting the number of retweet by day is not possible natively: Day 1: 200 Day 2: 100 On current workaround would be to do a date rage facet to get the date slots and ask only for the retweet field and compute the sums in the client. We could compute other stats like average, etc... too The closest I could see was https://issues.apache.org/jira/browse/SOLR-4772but it seems to be slightly different. Basically I am trying to do something very similar to the Date Histogram Facet<http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-facets-date-histogram-facet.html#search-facets-date-histogram-facet>in ES. Is there a way to move the counting logic to the Solr server? Thanks! Romain
