这是一个创建于 4283 天前的主题，其中的信息可能已经有所发展或是发生改变。
现在我们课题组开发了一个电子产品搜索推荐系统，希望收集一些真实的用户反馈，所以在这里我们同学们在空闲之余帮忙体验一下这款系统（用户可以选择购买电子产品，例如相机，笔记本）。
下面是大体的介绍（其中的500元港币我们可以换算成人民币交付）
============================================================
Dear Students,
We kindly invite you to take part in our experiment, which aims at studying how users search for products (e.g., digital cameras or laptops) in online stores.
To make it worth your while, the first 60 participants who successfully complete this experiment will be entered into a lottery for three prizes (each is in value of 500 HKD). It could be you!
If you are interested in, please click the following link to start the experiment (the whole process will take around 30 minutes):
http://128.199.240.194:8888/study
Due date: **March 31, 18:00**, 2014.
We look forward to your participation, and thanks for your time and contribution in advance!
Best Regards,

| 12 wangfengmadking OP @ted05 你确定不是你勿点了关闭按钮？如果你完成了整个实验流程，系统会给出一个thanks页面，里面有一个关闭页面的按钮。我们不会自动关闭页面的。 |

| 14 wangfengmadking OP @chau 确实存在这个问题，可能是由于mongodb的使用不当有关。由于第一次使用mongodb，发现这东西里面有好多坑呀。 |
