mini搜索引擎，载入50个文本文件，然后通过输入关键词来计算词出现的次数-we will design and implement a mini search engine that is used to search through a set of 50 documents and a set of sample queries. The data structures used for storing is vector and array. The algorithm in this project is two times traversal. The documents store will eliminate the stop words. The purpose of this project is to provide an overview of how a search engine works and gain hands-on experience in using data structure.
