Francesco Mari commented on OAK-7834:
-------------------------------------
The first version of the patch implements a {{search}} command that scans the
Segment Store for nodes with certain characteristics and prints their record
IDs on stdout. Finding the super-root nodes at the moment is a specific
solution to the more general problems of finding a node with two children named
{{checkpoints}} and {{root}}. For this reason, I opted for a very simple
interface to search nodes based on children names, property names, and property
values.
For example, finding the super-roots using the heuristic of the children named
{{checkpoints}} and {{root}} is equivalent to:
{noformat}
java -jar oak-run.jar search path/to/store -c checkpoints -c root
{noformat}
Moreover, it is possible to find nodes with specific property values. For
example, to find every node whose {{jcr:primaryType}} property is set to
{{cq:Page}}, a user can invoke:
{noformat}
java -jar oak-run.jar search path/to/store -v jcr:primaryType=cq:Page
{noformat}
