是否可以查询ScriptDb以仅返回具有特定属性/密钥的那些对象？
results = db.query({key: db.not(null)}); // always triggers error "We're sorry, a server error occurred. Please wait a bit and try again."
results = db.query({key: db.not(undefined)}); // returns all objects in the database
反之亦然：
results = db.query({key: undefined});
results = db.query({key: null}); // both these cause an error on any of the ScriptDbResult methods "Your query object contains an invalid component."
有什么想法吗？
