Solve the following python programming problem given the following code:
def boolean_operator_query(boolean_operator) : 
    'Generate boolean operator checking function.' 
    def _boolean_operator_query(expressions) : 
        'Apply boolean operator to expressions.' 
        def _apply_boolean_operator(query_function, expressions = expressions) : 
            'Return if expressions with boolean operator are satisfied.' 
            compiled_expressions = [compile_query (e) for e in expressions] 
            return reduce (boolean_operator, [e (query_function) for e in compiled_expressions]) 
return _apply_boolean_operator 
return boolean_operator
