------------------------------------------------------------------
We are still experiencing this issue with Lucene 9.x:
In our case the query
{{(spanNear([body:the, spanOr([body:domain, spanNear([body:domain, body:name,
body:system], 0, true)]), body:is], 0, true) in 1)}}
matches the doc: "the domain is", but doesn't match the doc "the domain name
system is"

> Project: Lucene - Core
> Issue Type: Bug
> Components: core/search
> Affects Versions: 5.5
> Reporter: Christoph Goller
> Assignee: Alan Woodward
> Priority: Critical
> Attachments: LUCENE-7398-20160814.patch, LUCENE-7398-20160924.patch,

> Example for a nested SpanQuery that is not working:
> Document: Human Genome Organization , HUGO , is trying to coordinate gene
> mapping research worldwide.
> Query: spanNear([body:coordinate, spanOr([spanNear([body:gene, body:mapping],
> 0, true), body:gene]), body:research], 0, true)
> The query should match "coordinate gene mapping research" as well as
> "coordinate gene research". It does not match "coordinate gene mapping
> research" with Lucene 5.5 or 6.1, it did however match with Lucene 4.10.4. It
> probably stopped working with the changes on SpanQueries in 5.3. I will
> attach a unit test that shows the problem.
