    Description copied from class: Query
    
    Expert: Constructs an appropriate Weight implementation for this query.
    Only implemented by primitive queries, which re-write to themselves.
    
    Overrides:
    
    createWeight in class Query
    
    scoreMode - How the produced scorers will be consumed.
    
    boost - The boost that is propagated by the parent queries.
    
    Throws:
    
    java.io.IOException
