Description

Currently IndexTracker while checking for index state updates does a diff till indexPath. For e.g. if index is /oak:index/fooIndex then it would create a SubtreeEditor for path /oak:index/fooIndex and refreshes the index if any change is found under that path.

With synchronous lucene property indexes now other changes would occur under /oak:index/fooIndex/:property-index which causes the tracker to refresh the index even if no change has occurred in main index. This is mitigated to some extent with OAK-6713 and its use in IndexTracker but not complete.

For proper fix the diff should check for changes in :status node
