Thomas Mueller updated OAK-6897: -------------------------------- Fix Version/s: (was: 1.22.0) > XPath query: option to _not_ convert "or" to "union" > ---------------------------------------------------- > > Key: OAK-6897 > URL: https://issues.apache.org/jira/browse/OAK-6897 > Project: Jackrabbit Oak > Issue Type: Improvement > Components: query > Reporter: Thomas Mueller > Assignee: Thomas Mueller > Priority: Trivial > > Right now, all XPath queries that contain "or" of the form "@a=1 or @b=2" are > converted to SQL-2 "union". In some cases, this is a problem, specially in > combination with "order by @jcr:score desc". > Now that SQL-2 "or" conditions can be converted to union (depending if union > has a lower cost), it is no longer strictly needed to do the union conversion > in the XPath conversion. Or at least emit different SQL-2 queries and take > the one with the lowest cost. -- This message was sent by Atlassian Jira (v8.3.4#803005)
