make a interface/facade here?

controllers.py

@app.route('/search', methods=['POST'])
def handle_search_call():
    # todo implement facade for request
    q = db_session.query(SubscriberTable.first_name,
                         SubscriberTable.last_name,
                         SubscriberTable.last_open,
                         SubscriberTable.email,
                         SubscriberTable.company).\
        join(SubscriberBriefProfileTable)
    for k, v in request.json:
        q = q.filter(getattr(SubscriberTable, v).like("%%%s%%" % v))
    q = q.limit(20)  # todo raise limit
    # result set
    result_set = q.all()
