As soon as I have learned the related technology in search engine, I implemented a simple search engine together with my friends as a practice. In this search engine, we implemented web page crawling, word segmentation, inverted list, binary search tree and many other technologies in mature search engine. Through this practical work, we improved ourselves much and became skilled in web search fields. We called it 'Nani' to represent our pursue for further knowledge and practical skills.
Here are some screen shot of this program.
