Subject [jira] [Commented] (OAK-420) Query: Lucene index problem with isdescendantnode
Date Tue, 08 Jan 2013 15:44:12 GMT

    [ https://issues.apache.org/jira/browse/OAK-420?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13546950#comment-13546950
] 

Alex Parvulescu commented on OAK-420:
-------------------------------------

it appears that the problem magically solved itself in the meantime. the sql2 test now fails
because of an "explain" test that is included in the "sql2" test suite:

{code}
explain select b.[jcr:path] as [jcr:path], b.[jcr:score] as [jcr:score], b.* from [nt:base]
as a inner join [nt:base] as b on ischildnode(a, b) where name(a) = 'yes' and isdescendantnode(a,
'/test') and b.[x] is not null
[nt:base] as [a] /* :path:/test/* where (name([a]) = cast('yes' as string)) and (isdescendantnode([a],
[/test])) */ inner join [nt:base] as [b] /* x:{* TO *} where [b].[x] is not null */ on ischildnode([a],
[b])
{code}

-> :path:/test/* is the culprit

maybe we can move the explain test to the "explain" suite so that I can reenable the lucene
sql2 tests.

> Using isdescendantnode seems to be problematic with the Lucene index currently.
> Adding isdescendantnode to some of the queries in sql2.txt and sql2_measure.txt works
for
> other index implementations, but breaks the LuceneIndexQueryTest.
> I believe the problem is isdescendantnode, but I'm not completely sure.
