有很大一个电子图书馆，里面每本书的每一页都是OCR转换出来的text，所有每页大 约有5%的error（转换错误，错误分割单词，跳脱。。。）。设计一个方法判定图书馆 里是否有完全一样的书（duplicate），或者将来有书进来时判定同样的书是否已存在。

Solution

Very large string matching, we mush use hashing or similar technique. Since books have error, we need to do fuzzy search/matching. Bloom filter is designed to do this!

Refer to [Design] Big Data – Fuzzy Search Url (Bloom Filter).
