> [~mattweber] pointed out on LUCENE-8196 that {{Intervals.unordered()}} doesn't check to see if its subintervals overlap, which means that for example {{Intervals.unordered(Intervals.term("a"), Intervals.term("a"))}} would match a document with {{a}} appearing only once.  This ticket will introduce a new function, {{Intervals.unordered_distinct()}}, that ensures that all subintervals within an unordered interval do not overlap.
