Ryan McKinley commented on SOLR-2366:
-------------------------------------
bq. sometimes you want percentage buckets
This does not map easily since you need to know the min/max value before
traversing -- it may actually take two passes.
The use case I am looking at is trying to show reasonable histograms for field
values, without really knowing much about the field values as input. Currently
I run the stats component, and then in a second query facet within that range
-- gets the job done, but not ideal.

> There really is no reason why the range gap for date and numeric faceting
> needs to be evenly spaced. For instance, if and when SOLR-1581 is completed
> and one were doing spatial distance calculations, one could facet by function
> into 3 different sized buckets: walking distance (0-5KM), driving distance
> (5KM-150KM) and everything else (150KM+), for instance. We should be able to
> quantize the results into arbitrarily sized buckets. I'd propose the syntax
> to be a comma separated list of sizes for each bucket. If only one value is
> specified, then it behaves as it currently does. Otherwise, it creates the
> different size buckets. If the number of buckets doesn't evenly divide up
> the space, then the size of the last bucket specified is used to fill out the
> remaining space (not sure on this)
> For instance,
> facet.range.start=0
> facet.range.end=400
> facet.range.gap=5,25,50,100
> would yield buckets of:
> 0-5,5-30,30-80,80-180,180-280,280-380,380-400
