Description

Currently, suggestions are indexed at index level - so, when querying for suggestions, the result incorporates all documents indexed by that document.

So, this doesn't allow filtering suggestions for a subset of indexed document - at least we should be able to get filtered suggestion based on a root path.

This seems very similar to a functionality provided by lucene vide LUCENE-5528 which was fixed in lucene 4.8. Since oak is still on 4.7, so, we can't exploit that feature.
