摘要： XML table indexes provide a more efficient mechanism for searching data stored in aggregate form. XML table indexes are a set of tables created to project out in column form commonly sought metadata from stored XML documents. By projecting the data includes into column form, queries on the XML documents can be efficiently processed as they can leverage the enhanced functionality provided by the database tables. The XML table indexes may use aliases, partitioning, constraints and other functions to further improve query flexibility and performance.

摘要： A web crawler indexes documents including information about document contents and metadata including information such as a URL. However, some applications rely on URL's that change frequently or are constructed to include user information so that the contents retrieved is customized to the user. An approach is provided for storing generic URL's in an index at crawl time, which are customized for the user at search time. A callback mechanism may be used to dynamically transform the generic URL into a URL that is specific to the user issuing the query and/or includes current information that may change frequently. In this way, when the query or search results are returned to the user, the user receives links that are active and valid for that particular user, directing the user to the appropriate site, application, etc. without requiring continuous updating of a very large index.

摘要： A flexible and extensible architecture allows for secure searching across an enterprise. Such an architecture can provide a simple Internet-like search experience to users searching secure content inside (and outside) the enterprise. The architecture allows for the crawling and searching of a variety or sources across an enterprise, regardless of whether any of these sources conform to a conventional user role model. The architecture further allows for security attributes to be submitted at query time, for example, in order to provide real-time secure access to enterprise resources. The user query also can be transformed to provide for dynamic querying that provides for a more current result list than can be obtained for static queries.
摘要翻译： 灵活可扩展的架构允许跨企业进行安全搜索。 这样的架构可以为在企业内部（和外部）搜索安全内容的用户提供简单的类似Internet的搜索体验。 该架构允许在整个企业中爬行和搜索各种或多个源，无论这些源是否符合常规用户角色模型。 该体系结构进一步允许在查询时提交安全属性，例如为了提供对企业资源的实时安全访问。 用户查询也可以被转换以提供动态查询，其提供比静态查询可获得的更多当前结果列表。

摘要： Version indicators within an existing range can be associated with a data partition in a distributed data store. A partition reconfiguration can be associated with one of multiple partitions in the data store, and a new version indicator that is outside the existing range can be assigned to the reconfigured partition. Additionally, a broadcast message can be sent to multiple nodes, which can include storage nodes and/or client nodes that are configured to communicate with storage nodes to access data in a distributed data store. The broadcast message can include updated location information for data in the data store. In addition, a response message can be sent to a requesting node of the multiple nodes in response to receiving from that node a message that requests updated location information for the data. The response message can include the requested updated location information.

摘要： Systems and methods that supply poll based notification system in a distributed cache, for tracking changes to cache items. Local caches on the client can employ the notification system to keep the local objects in sync with the backend cache service; and can further dynamically adjust the “scope” of notifications required based on the number and distribution of keys in the local cache. The server can maintain the changes in an efficient fashion (in blocks) and returns the changes to clients that perform the appropriate filtering. Notifications can be associated with a session and/or an application.

摘要： Techniques are described herein for storing instances of data among nodes of a distributed store based on hierarchical scale unit values. Hierarchical scale unit values are assigned to the respective nodes of the distributed store. A first instance (e.g., a primary instance) of a data module is stored in a first node having a first hierarchical scale unit value. A primary instance of the data module with respect to a data operation is an instance of the data module at which the data operation with respect to the data module is initiated or initially directed. A second instance (e.g., a primary or secondary instance) of the data module is stored in a second node having a second hierarchical scale unit value based on a magnitude of a difference between the first hierarchical scale unit value and the second hierarchical scale unit value. A secondary instance is essentially a “back-up” instance.
摘要翻译： 本文描述了用于基于分级比例单位值来存储分布式存储的节点之间的数据实例的技术。 分层比例单位值被分配给分布式存储的相应节点。 数据模块的第一实例（例如主要实例）被存储在具有第一分级比例单位值的第一节点中。 关于数据操作的数据模块的主要实例是数据模块的实例，在该实例中数据模块相对于数据模块的数据操作被启动或初始定向。 数据模块的第二实例（例如，主要或次要实例）基于第一分级比例尺单位值和第二分级比例单位值之间的差值的大小被存储在具有第二分级比例单位值的第二节点中 。 次要实例本质上是一个“备份”实例。

摘要： Systems and methods that supply a replication layer/agent that is generic to supporting a plurality of storage configuration as part of a distributed store. Such distributed store employs a Common Availability Substrate (CAS) for data transport and consistency, to render the distributed store scalable and available. Such an arrangement enables continuous operation of the store, while the replication subsystem creates new replicas (e.g., for load balancing, failover, and the like).
