Hi, In the "advanced" patch attached to OAK-1894 (https://issues.apache.org/jira/secure/attachment/12650790/OAK-1894-advanced.diff), I added a new method to IndexPlan which allows a PropertyDescription to be attached to the plan. With that patch, PropertyIndex reads the description out later (in query() and getPlanDescription()) to determine how to execute that query.
WDYT?
