Dawid Weiss commented on LUCENE-7848:
-------------------------------------

Hi Jim. Thanks for the analysis -- I do understand these two queries should be 
identical, but they have a different match result -- that's why I thought it's 
probably a span query issue rather than the builder's (whether you pull those 
gaps or push them inside the or shouldn't matter).

This time I'm on holidays, but I'll keep looking at LUCENE-7389, perhaps it 
sheds some light on what's going on.

> QueryBuilder.analyzeGraphPhrase does not handle gaps correctly

> Position increments greater than 1 are ignored when the query builder creates 
> a graph phrase query. 
> Instead it should use SpanNearQuery.addGap for pos incr > 1.
