Tomás Fernández Löbbe commented on SOLR-6216:
---------------------------------------------
Thanks for committing this Erick. I tested this in 4x and tests are passing
too. The only thing that needs to be added in addition to the merge is
"Lucene3x" to the list of codecs to skip (in DistributedIntervalFacetingTest
and TestIntervalFaceting)
> Better faceting for multiple intervals on DV fields

> There are two ways to have faceting on values ranges in Solr right now:
> “Range Faceting” and “Query Faceting” (doing range queries). They both end up
> doing something similar:
> {code:java}
> searcher.numDocs(rangeQ , docs)
> {code}
> The good thing about this implementation is that it can benefit from caching.
> The bad thing is that it may be slow with cold caches, and that there will be
> a query for each of the ranges.
> A different implementation would be one that works similar to regular field
> faceting, using doc values and validating ranges for each value of the
> matching documents. This implementation would sometimes be faster than Range
> Faceting / Query Faceting, specially on cases where caches are not very
> effective, like on a high update rate, or where ranges change frequently.
> Functionally, the result should be exactly the same as the one obtained by
> doing a facet query for every interval
