问题：推荐效果很差

[kiang-codes]

用户对三个商品有feedback，而且仅有三个。
问题1：为什么在基于类别推荐时，标签相似度最高的商品排在了最后一个
问题2：这个商品三个标签都中了，但是在综合推荐时，根本没有推荐出来（后台标签的推荐已经设置为true）
很期待您的回答，谢谢！

The user has feedback on three items, and only three.
Question 1: Why is the product with the highest label similarity ranked last when recommending based on categories
Question 2: This product has been selected in all three tags, but it is not recommended at all in the comprehensive recommendation (the recommendation of the background tag has been set to true)
Looking forward to your answer, thank you!

如果你想要推荐标签相似的物品，那么需要这样配置强制系统使用标签推荐

[recommend.offline]
enable_latest_recommend = false
enable_popular_recommend = false
enable_user_based_recommend = false
enable_item_based_recommend = true
enable_collaborative_recommend = false
enable_click_through_prediction = false

感谢您的回答，但是这样的其实很难符合实际应用，item-base推荐是我们场景的一个重要推荐，但是数量有限，而且每天上新货品也需要推。 我也在想办法解决这个问题！
