This is JavaEye's early search service, implemented using Lucene. We then encapsulated it with our own custom service. The core content recommendation system used the TF/IDF algorithm, which is actually quite simple, but incredibly effective. The entire search service's codebase is small, yet it delivers excellent results, making it a prime example of a refined and compact system.

这是 JavaEye 早年的搜索服务，使用 lucene 实现的，然后自己写了服务进行了封装，核心的内容推荐系统，用的是 TF / IDF 算法， 其实很简单，但是效果超级好。整个搜索服务的代码量也不大，但是效果很好，是精致小巧的典范。
