Search engine become the most commonly used information retrieval tool, it involves a database, information retrieval, artificial only, data mining, Java, natural language processing and other fields of theory and technology. Traditional search engine results retrieved for any users are the same, without taking into account the user's interest in the issue. Therefore, search results often do not meet the needs of users, users often require vast amounts of search results to filter the information they need, so spend a lot of time.
