    Description

      In OAK-4265 a limited form of "union" for XPath was added. However, union queries that contain "or" are not converted properly. For example:

      //*[@a=1 or @b=1]
select [jcr:path], [jcr:score], * from [nt:base] as a where [a] = 1 
union select [jcr:path], [jcr:score], * from [nt:base] as a where [b] = 1

      but

      (//*[@a=1 or @b=1] | //*[@c=1])
select [jcr:path], [jcr:score], * from [nt:base] as a where [a] = 1 or [b] = 1 
union select [jcr:path], [jcr:score], * from [nt:base] as a where [c] = 1

      It should be converted to:

      select [jcr:path], [jcr:score], * from [nt:base] as a where [a] = 1 
union select [jcr:path], [jcr:score], * from [nt:base] as a where [b] = 1 
union select [jcr:path], [jcr:score], * from [nt:base] as a where [c] = 1
