Alan Woodward commented on LUCENE-8622:
---------------------------------------
Attached is a patch containing a MinimumShouldMatchIntervalIterator, currently
available via {{Intervals.atLeast}}. As well as being useful for these type of
queries, I think this would also be handy for building a proximity boosting
query, by iterating over subspans of a set of terms as a sort of very crude
query segmentation.

> It would be useful to be able to search for intervals that span some subgroup
> of a set of iterators, allowing us to build a 'some of ' or 'at least'
> operator - ie, search for terms that appear near at least 3 of a list of 5
> terms.
