    • A system receives a search query, determines whether the received search query includes an entity name, and determines whether the entity name is associated with a common word or phrase. When the entity name is associated with a common word or phrase, the system generates a link to a rewritten query, performs a search based on the received search query to obtain first search results, and provides the first search results and the link to the rewritten query. When the entity name is not associated with a common word or phrase, the system rewrites the received search query to include a restrict identifier associated with the entity name, generates a link to the received search query, performs a search based on the rewritten search query to obtain second search results, and provides the second search results and the link to the received search query.
    • 系统接收搜索查询,确定接收到的搜索查询是否包括实体名称,并确定实体名称是否与公共单词或短语相关联。 当实体名称与通用单词或短语相关联时,系统生成到重写查询的链接,基于接收到的搜索查询执行搜索以获得第一搜索结果,并提供第一搜索结果和重写的链接 查询。 当实体名称不与公共词或短语相关联时,系统重写接收到的搜索查询以包括与实体名称相关联的限制标识符,生成到所接收的搜索查询的链接,基于重写的搜索查询执行搜索 获得第二搜索结果,并提供第二搜索结果和链接到所接收的搜索查询。

    • Methods and apparatus are described for scoring documents in response, in part, to parameters related to the document, source, and/or cluster score. Methods and apparatus are also described for scoring a cluster in response, in part, to parameters related to documents within the cluster and/or sources corresponding to the documents within the cluster. In one embodiment, the invention may identify the source; detect a plurality of documents published by the source; analyze the plurality of documents with respect to at least one parameter; and determine a source score for the source in response, in part, to the parameter. In another embodiment, the invention may identify a topic; identify a plurality of clusters in response to the topic; analyze at least one parameter corresponding to each of the plurality of clusters; and calculate a cluster score for each of the plurality of clusters in response, in part, to the parameter.
