> interval faceting has a different implementation than range faceting based on DocValues API. This is sometimes faster and doesn't rely on filters / filter cache.
> I'm planning to add a "method" parameter that would allow users to choose between the current implementation ("filter"?) and the DV-based implementation ("dv"?). The result for both methods should be the same, but performance may vary.
> Default should continue to be "filter".
