Shalin Shekhar Mangar commented on SOLR-7795:
---------------------------------------------
Thanks [~tomasflobbe] and [~liahsuan]. Reading the comments, it is not clear to
me whether Hoss's comments are incorporated or not:
# I have described a new output format in SOLR-6352 which could be used for
this feature instead of having separate "counts" and "intervals". Perhaps we
introduce that format first (maybe independently of hanging stats off of
ranges) and then merge this feature into the same format?
# Also, can the "f.price.facet.range.set" params work as local params now?

> Now that range faceting supports a "filter" and a "dv" method, and that
> interval faceting is supported on fields with {{docValues=false}}, I think we
> should make it so that interval faceting is just a different way of
> specifying ranges in range faceting, allowing users to indicate specific
> ranges.
> I propose we use the same syntax for intervals, but under the "range"
> parameter family:
> {noformat}
> facet.range=price&
> f.price.facet.range.set=[0,10]&
> f.price.facet.range.set=(10,100]
> {noformat}
> The counts for those ranges would come in the response also inside of the
> "range_facets" section. I'm not sure if it's better to include the ranges in
> the "counts" section, or in a different section (intervals?sets?buckets?).
> I'm open to suggestions.
> {code}
> "facet_ranges":{
> "price":{
> "counts":[
> "[0,10]",3,
> "(10,100]",2]
> }
> }
> {code}
> or…
> {code}
> "facet_ranges":{
> "price":{
> "intervals":[
> "[0,10]",3,
> "(10,100]",2]
> }
> }
> {code}
> We should support people specifying both things on the same field.
> Once this is done, "interval faceting" could be deprecated, as all it's
> functionality is now possible through range queries.
