Date Fri, 03 Nov 2017 12:12:00 GMT

Davide Giannella commented on OAK-1980:

[~mreutegg], [~chetanm] with all the efforts we're currently going with lucene property index
and the fact that this has been sitting for three years, do you consider this as still needed?

> Oak is able to maintain indexes on any location in the hierarchy. However the lookup
for most index implementations only make use of an index under the root node. There are various
TODOs in the code regarding this, e.g. in PropertyIndex. Looking up an index along the filter
path adds some additional cost, but should be within reasonable bounds.
