> In OAK-4265 a limited form of "union" for XPath was added. However, union queries that contain "or" are not converted properly. For example:
> {noformat}
> //*[@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
> {noformat}
> but
> {noformat}
> (//*[@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
> {noformat}
> It should be converted to:
> {noformat}
> 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 
> {noformat}
