>                 URL: https://issues.apache.org/jira/browse/OAK-955
>             Project: Jackrabbit Oak
>          Issue Type: Bug
>          Components: core, query
>            Reporter: Alex Parvulescu
>            Assignee: Thomas Mueller
>            Priority: Minor
>              Labels: performance, resilience
>             Fix For: 1.3.7

> Example query:
> {code}
> SELECT a.* 
> FROM [nt:unstructured] AS a 
> INNER JOIN [nt:unstructured] AS b 
> ON b.[jcr:uuid] = a.testref 
> WHERE a.type = 'child' 
> AND (CONTAINS(a.*, 'testJoinWithOR4') OR b.type = 'parent' AND CONTAINS(b.*, 'testJoinWithOR4'))
> {code}
> I'm not sure why this happens, but I noticed stepping through the code that the filter
generated on the query doesn't contain any fulltext constraints. It does however contain the
'type' info which will trick the query engine into picking a property index, failing the test
because is returns more results than it should.
> See failing tests on the lucene module:

>  - org.apache.jackrabbit.core.query.JoinTest#testJoinWithOR5
