Ok. My fault. Old sport, you know. When retrieving intermediate scopes,
parents bitmask shout include all enclosing scopes as well. It's a dark side of
the BJQ.
{!parent which=`class:(section OR composition)`}<grand children qry> I'm not
sure what you try to achieve specifying grandchildren as a parent-bitmask.
Note, the algorithm assumes that parents' bitmask has the last doc in the
segment set. I.e. 'which' query supplied in runtime should strictly correspond
to the block structure indexed before.
