摘要：
Documents returned by a search engine may be good keyword matches to the search query terms, but may not historically have been very effective in addressing user needs. Documents which have historically been effective in addressing user needs are said to have high efficacy. Disclosed are methods that try to assess the beginning and ending of user search sessions, assume that documents that are the last document looked at are those with the highest efficacy, and incorporate this notion of efficacy in returning-search results.
