Lets say you wanted to do ranges over some integer. Simply convert those integers to dates, such as java.time.Instant.ofEpochSecond(myInteger).toString(). It's more efficient to convert to seconds (as in this example) as a base instead milliseconds because the internal date oriented tree has 1000 leaves at the millisecond level to aggregate to the next higher (second). Also keep in mind you have to work within a signed Long space.
Longer term, hopefully someone will add a Solr adapter to Lucene's new IntRangeField (and *RangeField variants) which is for general use. I'm not sure if LongRangeField would be faster than DateRangeField as the approaches are internally quite different. It probably would be. The other factor is index size, and I think those new range fields would generally be leaner. ~ David On Fri, Nov 25, 2016 at 4:18 PM O.
