Review comment:
It is extremely useful to capture and drill down in the context of
another query. Let's say apples nearby oranges. Yes, you can achieve a similar
thing with other queries but it's pretty useful on its own (because you can
first inspect the context you're looking at by running the extends query in
isolation).
I've modified flexible query parser and added those functions as
prefix-scoped "language". Looks like this:
https://get.carrotsearch.com/lingo4g/1.12.0-SNAPSHOT/doc/#interval-functions
And combine with the matches highlighter it really shines. It's the best
when you get multiple overlapping intervals; I don't have an example won this
computer (I have a day of on home duties) but I can send you one later on - you
can do some really impressive stuff with intervals!
