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： A messaging entity configured in a memory of first node of a plurality communicatively coupled nodes is disclosed. The nodes are included in a distributed computing system. The messaging entity is configured to operate as a secondary messaging entity in a messaging server for the plurality communicatively coupled nodes. The messaging entity is communicatively couple to a primary messaging entity configured in a memory of a second node of the plurality of nodes. The primary messaging entity is configured to store a message; store a copy of the message. Also, the messaging entity is configured to be promoted to a new primary messaging entity in the event of failure of the primary messaging entity.

摘要： Search term ranking algorithms can be generated and updated based on customer settings, such as where a ranking algorithm is modeled as a combination function of different ranking factors. An end user of a search system provides personalized preferences for weighted attributes, generally or for a single instance of the query. The user also can indicate the relative importance of one or more ranking factors by specifying different weights to the factors. Ranking factors can specify document attributes, such as document title, document body, document page rank, etc. Based on the attribute weights and the received user query, a ranking algorithm function will produce the relevant value for each document corresponding to the user preferences and personalization configurations.

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 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.

摘要： In response to a request including a state object, which can indicate a state of an enumeration of a cache, the enumeration can be continued by using the state object to identify and send cache data. Also, an enumeration of cache units can be performed by traversing a data structure that includes object nodes, which correspond to cache units, and internal nodes. An enumeration state stack can indicate a current state of the enumeration, and can include state nodes that correspond to internal nodes in the data structure. Additionally, a cache index data structure can include a higher level table and a lower level table. The higher level table can have a leaf node pointing to the lower level table, and the lower level table can have a leaf node pointing to one of the cache units. Moreover, the lower level table can be associated with a tag.

摘要： Systems and methods that designate read/write consistency models based on requirements of a distributed store to increase performance or scale. Such sever loads can be determined via a plurality of mechanisms, including delays in responses by the primary node; setting predetermined threshold limits that if exceeded results in contacting secondary nodes; polling services of the distributed cache periodically and maintaining track of loads on the servers, and the like. The weak or scalable read can occur when read requests are directed to a secondary node, and upon over loading of the primary node.

摘要： Systems, methods, and other embodiments associated with extracting knowledge from application data and maintaining an ontology based on the extracted knowledge are described. One example system includes a mapping logic to store mappings between application objects and ontology classes and an information extraction (IE) logic that accesses the mapping logic to identify application data to process based on the mappings. The application data may be stored in application data repositories belonging to an enterprise and may be characterized by the application object. Having identified application data to process, the IE logic may locate data in the application data repositories and selectively manipulate an ontology based on selected application data elements.

摘要： Techniques are described herein for managing access to a distributed cache during garbage collection. When garbage collection is to be performed with respect to a node, the node may send a request to a data manager requesting to have an instance of data module(s) included in the node that are in a primary state placed in a secondary state. The data manager may change the state of the data module(s) to the secondary state. The data manager may change the state of another instance of the data module(s) that is included in another node to the primary state. When the garbage collection is complete with respect to the node, the node may send another request to the data manager requesting that the data module(s) that were placed in the secondary state be returned to the primary state. The data manager may return those data module(s) to the primary state.

摘要： Systems, methods, and other embodiments associated with logically expanding a document and determining the relevance of the logically expanded document to a query are described. One method embodiment includes searching an index to locate a document identifier for a document in which a query term appears. The method includes determining whether the index entry includes an expansion identifier, and, if so, producing a logically expanded document. The logically expanded document may include both a document associated with the document identifier and a document associated with the expansion identifier. The method may then determine a relevance value of the logically expanded document with respect to the query and may provide a signal corresponding to the relevance value.
