When a user uses search engine to search for documents with a query in repository, the search result may be a list of ranked documents, and these documents may contain a lot of relationship in term of the specific query. If the user clicks some search result further, and if the click and open operation meet certain conditions, for example exceed a period of time, the clicked document could be deemed as related to the search query.
