> {{--doc-traversal-mode}} works on the notion of {{preferred}} children which is computed using path fragments that form aggregate rules.
> The idea is reading through aggregated paths should avoid keeping non useful nodes (for path being currently indexed) in memory.
> But, currently, in case, say when there multiple preferred children - {{jcr:content}}, {{metadata}}, then an index defn indexing parent of a very deep tree root would try to read in the whole tree before concluding that it doesn't have preferred children
> e.g. with preferred list - {{jcr:content}} and {{metadata}} and index looking for {{jcr:content}} indexing following structure
> {noformat}
> + /path/being/indexed
> + very
> + very
> + very
> + deep
> + tree
> + /some-sibling
> {noformat}
> Currently, while looking for {{jcr:content}}, the code concludes that it doesn't exist only after reaching {{/some-sibling}} (or if number of children read of {{/path/being/indexed}} is >= num_preferred_children).
