    Description

      CustomScoreQuery.java, doExplain has the following line:

      res.addDetail(new Explanation(getBoost(), "queryBoost"));
      

      This multiplies the custom score query by just the boost of the current query, and not by

      queryWeight=topLevelBoost*getBoost();
      

      which is the value that's actually used during scoring. This leads to drastically different scores in the debug info, relative to the actual score, when the query is a subquery of another one, like a BooleanQuery clause, with a non-1 boost.
