Search engine based on web crawler

In this project, I developed a personalized search engine with based on the web crawler, once I start the search engine, it will crawl the particular URL first and store all data into memory for searching later, the data structure I used in here is Inverted Index.

For every users, they will have basic user profile, including login, logout and change password function, allowed users to perform searches and maintain searched query history and visited links.

There is a dynamic top 10 query word in the right side of the page, which is updating immediately once every query word got searched, the most used query word will set to be No.1 in the top 10 query words.
