> 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}
