by the way, probably there's room for some optimization, e.g. very simple
idea: exclude paths at depth 1 (children of root node) the principle is not
able to read (which may mean adding them to the query passed to the Index
implementation), if any, then you'd always have to apply fine grained ACLs
on the result but maybe excluding some branches from start may help.

What limitation are you exactly referring to? Is it the BooleanQuery max
clause limit [1]?
