Vikas Saurabh updated OAK-6902:
-------------------------------
Description:
OAK-6735 introduced cost calculation based on number of documents indexed per
term. But, it miscalculates cost as 0 for relative properties which are queried
on an {{nt:base}} based index while tranforming paths
e.g. index:
{noformat}
+ index
+ indexRules/nt:base/properties/foo
- name = foo
- propertyIndex = true
{noformat}
and query
{noformat}
SELECT * FROM [nt:base] WHERE [a/foo] = 'bar'
{noformat}
