----------------------------------
Fix Version/s: (was: 1.12.0)
> Not always convert XPath "primaryType in a, b" to union
> -------------------------------------------------------
>
> Key: OAK-6309
> URL: https://issues.apache.org/jira/browse/OAK-6309
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: query
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Priority: Critical
> Fix For: 1.14.0
>
>
> Currently, queries with multiple primary types are always converted to a
> "union", but this is not alway the best solution. The main problem is that
> results are not sorted by score as expected. Example:
> {noformat}
> /jcr:root/content//element(*, nt:hierarchyNode)[jcr:contains(., 'abc)
> and (@jcr:primaryType = 'acme:Page' or @jcr:primaryType = 'acme:Asset')]
> {noformat}
> This is currently converted to a union, even if the same index is used for
> buth subqueries (assuming there is an index on nt:hierarchyNode).
> A workaround is to use:
> {noformat}
> /jcr:root/content//element(*, nt:hierarchyNode)[jcr:contains(., 'abc)
> and (./@jcr:primaryType = 'acme:Page' or ./@jcr:primaryType = 'acme:Asset')]
> {noformat}
