Alan Woodward commented on LUCENE-8477:
---------------------------------------

I like [~jpountz]'s suggestion just to document this.  Parser implementers can 
check for disjunctions with variable lengths and push those up the tree.

[~Martin Hermann] or [~gol...@detego-software.de] would this work for you?

> The current implementation of the disjunction interval produced by 
> {{Intervals.or}} is a direct implementation of the OR operator from the Vigna 
> paper.  This produces minimal intervals, meaning that (a) is preferred over 
> (a b), and (b) also over (a b).  This has advantages when it comes to 
> counting intervals for scoring, but also has drawbacks when it comes to 
> matching.  For example, a phrase query for ((a OR (a b)) BLOCK (c)) will not 
> match the document (a b c), because (a) will be preferred over (a b), and (a 
> c) does not match.
> This ticket is to discuss the best way of dealing with disjunctions.
