Search engine is very humane, it is usually the user search intent analysis When the user searches for some of the more general keywords, the search engine does not know exactly what the user needs only based on the keyword itself. At this time, the user is attempted to analyze the user's search intention. For example, the user searches for "Andy Lau", the search engine Do not know the user is in the end want to get Andy Lau's profile, the latest news, or Andy Lau's related videos, pictures, music, this time will trigger the search engine's integrated search function, can not determine the exact needs of users, then put "Andy Lau" related and different directions at the same time presented the content, allowing users the freedom to choose, so you can also ensure that the search results on the first page to meet the user's search needs, according to the statistical analysis of the content of the keyword search concerns the search engine The ranking of these content will also be adjusted. When users search for some common words, the search engine tries to refer to the user's geographical location and returns information that may be local to the user most in need. When a user repeatedly searches for a certain broad keyword (including extensions and synonyms), if the same webpage is clicked frequently, the search engine records the user's behavior through COOLIE. When the number of times the user searches for the click reaches a certain level After searching for relevant keywords, the search engine will prioritize the webpage that the user frequently browses, which is the "personalized" search result. http://www.3renseo.cn/
