Abstract: 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 of 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 received 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.

Abstract: Techniques are provided for scheduling data operations for a given query based upon a query-cost model that analyzes the cost of scheduling data operations based upon their operation cost and the type of resources needed for the operation. In an embodiment, a database server receives a set of operations for a query. The database server determines a set of leaf operation nodes from the set of data operations, where the set of leaf operation nodes includes operation nodes that do not depend on the execution of other nodes within the set of data operations. The database server compares operation costs between the leaf operation nodes to determine which leaf operation node to insert into a scheduled order set. The database server inserts the leaf operation node into the scheduled order set. Then the database server iteratively determines new leaf operation nodes and performs cost analysis on remaining leaf operation nodes to generate a set of scheduled data operations.

Abstract: A method of implementing a universal framework for searching across multiple search platforms in a secure federated search. The method includes receiving, at a federated broker, a query from an authorized user, obtaining a plurality of user credentials associated with the authenticated user, wherein each of the plurality of user credentials are used to access at least one source of a plurality of sources, determining a required query format for each of the plurality of sources, translating the query into a plurality of queries formatted according to the required query format of each of the plurality of sources, propagating the plurality of translated queries and the plurality of user credentials to each corresponding source to appear to each corresponding source to be the authorized user, receiving, at the federated broker, results of each of the plurality of queries from each source of the plurality of sources, and consolidating the results of each of the plurality of queries to be displayed in a uniform manner.

Abstract: 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 of 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.

Abstract translation: 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各种源，而不管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。
