Alex Parvulescu created OAK-955:
-----------------------------------
Summary: Query: Filter doesn't contain fulltext constraints from
joins
Key: OAK-955
URL: https://issues.apache.org/jira/browse/OAK-955
Project: Jackrabbit Oak
Issue Type: Bug
Components: core, query
Reporter: Alex Parvulescu
Priority: Minor
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#testJoinWithOR4
- org.apache.jackrabbit.core.query.JoinTest#testJoinWithOR5
