Paul Elschot commented on LUCENE-7398:
--------------------------------------
I applied the patch to master commit b3505298a5bef76ff83b269bf87a179d027da849 .
With the patch applied, TestSpanCollection does not compile, there is no
applicable createWeight() method a few times.
Probably there was a recent conflict there, so I could not actually verify the
patch.
> Nested Span Queries are buggy
> -----------------------------
>
> Key: LUCENE-7398
> URL: https://issues.apache.org/jira/browse/LUCENE-7398
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/search
> Affects Versions: 5.5, 6.x
> Reporter: Christoph Goller
> Assignee: Alan Woodward
> Priority: Critical
> Attachments: LUCENE-7398.patch, TestSpanCollection.java

> 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.
