Hi, Those are internal classes and not to be extended (not only the constructor is pkg-private, the whole class is: https://goo.gl/5WyLYz)! Scorers follow the delegator pattern. If you want to modify the behaviour of a Scorer, create a delegator scorer (e.g. some Filtering Scorer) and change its behaviour (e.g. filter additional documents,...). This can be done by a query that filters other querys. E.g. look at ConstantScoreQuery or similar queries that wrap other scorers.
Subclassing ConjunctionScorer would bring you nothing because internals are still private - and that's good.
