Subject ToParentBlockJoinQuery$BlockJoinWeight cannot explain match on parent document
Date Fri, 25 May 2012 11:20:14 GMT
Hello all,

I try to calculate score explanations for a query that contains a 
ToParentBlockJoinQuery and get the following exception:

cannot explain match on parent document


I can understand that the ToParentBlockJoinQuery cannot explain the 
scores of this document's children, but would it be possible not to 
throw an exception but to simply output the score this document got from 
its children? This would allow me to analyze the score obtained from 
other parts of the complete query, and if needed, I could still get an 
explanation on the childquery itself with a specific child id.

Should I open an issue for this, or is it impossible to output any kind 
of explanation (even a dummy explanation) in BlockJoinWeight?
