摘要： A search engine server system receives from a client system a search query and identifies a set of documents in accordance with the search query. A content snippet corresponding to content in a respective document of the identified set of documents is generated, the content snippet associated with at least one query term of the one or more query terms in the search query. A response to the search query is returned to the client system, the response including information identifying at least the respective document and including the content snippet. Generating the content snippet includes performing a first decompression operation on first token identifiers, from a compressed document repository, to provide a set of second token identifiers, and performing a second decompression operation on the set of second token identifiers to recover uncompressed content comprising a portion of the respective document.

摘要： A multi-stage query processing system and method enables multi-stage query scoring, including “snippet” generation, through incremental document reconstruction facilitated by a multi-tiered mapping scheme. At one or more stages of a multi-stage query processing system a set of relevancy scores are used to select a subset of documents for presentation as an ordered list to a user. The set of relevancy scores can be derived in part from one or more sets of relevancy scores determined in prior stages of the multi-stage query processing system. In some embodiments, the multi-stage query processing system is capable of executing one or more passes on a user query, and using information from each pass to expand the user query for use in a subsequent pass to improve the relevancy of documents in the ordered list.
摘要翻译：多级查询处理系统和方法通过多层次映射方案促进的增量文档重建实现了多阶段查询评分，包括“代码段”生成。在多阶段查询处理系统的一个或多个阶段，使用一组相关性分数来选择文档的子集，以作为用户的排序列表呈现。相关性分数的集合可以部分地从多级查询处理系统的先前阶段中确定的一组或多组相关性得分导出。在一些实施例中，多级查询处理系统能够执行用户查询的一个或多个传递，并且使用来自每个遍的信息来扩展用户查询以用于随后的传递中以改善订购中的文档的相关性列表。
