-----------------------------------
Summary: GQL queries with "jcr:primaryType='x'" don't use the node
type index
Key: OAK-1744
URL: https://issues.apache.org/jira/browse/OAK-1744
Project: Jackrabbit Oak
Issue Type: Improvement
Components: query
Reporter: Thomas Mueller
Priority: Minor
Fix For: 1.1
GQL queries (org.apache.jackrabbit.commons.query.GQL) with type restrictions
are converted to the XPath condition "jcr:primaryType = 'x'". This conditions
is not currently interpreted as a regular node type restriction in the query
engine or the node type index, as one would expect.
Such restrictions could still be processed efficiently using the property index
on "jcr:primaryType", but if that one is disabled (by setting the cost manually
very high, as it is done now), then such queries don't use the expected index.
I'm not sure yet where this should be best fixed.
