Abstract
A request is received that includes a primary keyword and a persistent keyword. In response to the request, a root page is found that includes a first term that matches the primary keyword. Descendant pages of the root page are searched for a second term that matches the persistent keyword. The search determines that the descendant pages are at levels on paths from the root page and that the levels are within a depth from the root page. A descendant page is found that is a descendant of the root page and that includes a second term that matches the persistent keyword. A root link that points at the root page and a descendant link that points at the descendant page are sent to the requester. If the number of times that the primary keyword was received is greater than a threshold number, then the primary keyword is added to the persistent keywords.
