    • Techniques are disclosed herein for providing a custom search engine. In one aspect, a first search query is received from a requestor. First search results contain search result items that match the first search query are obtained. A least one sub-query is generated from the first search results. The generating is based on rules for a particular custom search engine. Second search results that match the sub-query are then obtained. A search result set is formed from a corpus that includes the first search results and the second search results. The generating of the search result set is based on the rules for the particular custom search engine. The search result set is provided to the requester. In one aspect an interface for designing a custom search engine is provided. The interface allows the designer to specify the layout of a search results page.

    • A framework is provided for composing texts about objects with structured information about these objects, and thus disclosed are methodologies for linking information from at least two data sources—one comprising a plurality of documents comprising text pertaining to at least one object, and one comprising a plurality of structured records comprising at least one characteristic of the at least one object, each characteristic comprising one property name and an associated property value corresponding to the property name for the at least one object—by determining one or more instance-based traits for each object in both data sources and associating at least one record with at least one document that refers to each object, each trait comprising one or more characteristics that identifiably distinguish each object from all other objects.

    • Described is answering online web queries from a structured data store, such as a products database. An online web search query is modified into an evaluation expression for accessing a structured data store (e.g., a database, XML file, a flat table) to find search results. A query is matched to a pattern, which is used to generate the expression, as well as determine to which structured data store the query is routed. Tokens (e.g., words) in the query are processed against a dictionary of token classes (sets of tokens) and patterns (sets of token classes) to annotate the query to map the query to the matching pattern. A translation process generates the expression based on translation hints that correspond to the matching pattern. Also described is offline mining of query logs to generate the dictionaries.
    • 描述的是回答来自结构化数据存储(如产品数据库)的在线Web查询。 在线网络搜索查询被修改为用于访问结构化数据存储(例如,数据库,XML文件,平面表)以查找搜索结果的评估表达式。 查询与一个模式相匹配,该模式用于生成表达式,以及确定查询路由到哪个结构化数据存储。 根据令牌类(令牌集)和模式(令牌类集合)的字典处理查询中的令牌(例如,单词),以注释查询以将查询映射到匹配模式。 翻译过程基于与匹配模式对应的翻译提示生成表达式。 还描述了查询日志的离线挖掘以生成字典。

    • A message broker can allow any server in a cluster to publish to, and subscribe, to a message channel. A server subscribing to a channel can set up a message filter such that XQuery expressions can be used to filter against the messages arriving on the channel A message broker can also utilize a unique filtering algorithm to optimize data access. Static subscription information can be captured in order for a message broker to do client-side filtering. A message broker can also construct and maintain at least one table in memory that indicates whether any server in the cluster may ever do a dynamic subscription. For dynamic subscriptions, the publishing server can extract the information from a database, such as by executing a DBMS select on a subscription table using a primary key lookup.
    • 消息代理可以允许集群中的任何服务器发布到订阅消息通道。 订阅频道的服务器可以设置消息过滤器,使得XQuery表达式可以用于对抵达信道的消息进行过滤。消息代理还可以利用唯一的过滤算法优化数据访问。 可以捕获静态订阅信息,以便消息代理进行客户端过滤。 消息代理还可以构建和维护内存中至少一个表,指示集群中的任何服务器是否可能执行动态订阅。 对于动态订阅,发布服务器可以从数据库中提取信息,例如通过使用主键查找在订阅表上执行DBMS选择。
