Abstract: In some examples, a system may use content classes to manage indexing of object data. A content class may include a set of one or more content properties. Each content property may include a name, an expression for extracting data, and an expression type. When object data is received, such as for indexing, the expression type of each content property may be compared with the data type of the received data. Based at least in part on determining that the expression type matches the data type, the system may extract a data value from the received data in accordance with the expression. The system may save the extracted data value to a data structure in association with the name of the content property, and may subsequently use the data value and the name of the content property when creating an index for the object data.

Abstract: A data intake and query system may store raw machine data that includes location information. A client system may include a user interface for searching the data intake and query system. The user interface allows a user to define a field search query and to define one or more ad-hoc boundary regions on a map. A combined query is transmitted to the data intake and query system, the combined query including both the field search query and location search information that is based on the ad-hoc boundary regions. The data intake and query system runs the combined query and returns responsive results, which are displayed at the client user interface.

Abstract: A networked page access and addressing method to generate web pages responsive to requested client requests parses addresses of incoming requests into at least two logical segments: a first likely to represent a category and a second likely to represent a product. By generating hash values for the first segment, it can be compared against hashes in the internal directory to identify a local category corresponding to the represented in the address. If so, a local address can be generated by combining with the second segment with an identifier of that local category. Information from the data record at that local address can used to form a web page responsive to the request.

Abstract: The subject matter of this specification generally relates to reconciling conflicts between replicas of data. In one aspect, a system obtains a first document that includes a first replica of an object used by an application at a first device and a second document that includes a second replica of the object used by the application at a second device. The system generates a merged document from the first document and the second document. The system determines that the first value for the first key was modified at the first device at a later time than the first value for the first key was modified at the second device. In response, the system includes, in the merged document, the first value for the first key in the first document and, for each descendant element of the first element, a value for the descendant element's key in the first document.

Abstract: A discussion thread is associated with a master recipients list that is maintained at an author's computer or a server computer. The recipients list is revised as participants in the discussion are added to and/or removed from the discussion. An author is notified when target recipients do not match the master recipients list. When a participant is added to the discussion from an old discussion instance, a thread manager provides for the added participant to receive a more current discussion instance.

Abstract: This invention discloses a novel system and method for determining the genealogy of versions of a document by inspection of content extracted from the document. In one embodiment, the invention extracts a set of revision identifier values from each version of a document and then applies logical rules to the extracted set of revision identifier values to determine which versions of the document are ancestors of the other versions.

Abstract: Techniques are provided for inofile management and access control list file handle parity. For example, operations targeting a first storage object of a first node are replicated to a second storage object of a second node. A size of an inofile maintained by the second node is increased if an inode number to be allocated by the replication operation is greater than a current size of the inofile. Access control list file handle parity is achieved by maintaining parity between inode number and generation number pairings of the first node and the second node.

Abstract: Embodiments of the present disclosure relate to a data analysis system for grouping and enriching data items for presentation to an analyst through a user interface. Data items from one or more data sources are combined into memory-efficient clustered data structures, which may be stored as one or more data tables in a database. Analysis and scoring of those clustered data structures can be performed by utilizing various criteria or rules to generate scores, reports, alerts, or conclusions that may aid an analyst in evaluating the clustered data structures. The analysis and scoring may also be added to the clustered data structures which are stored as one or more data tables in a database. The analyst may be prompted to create a dossier format or specification and to additional enrichments to be performed on the raw data items in the clustered data structures. The system may then search, group, or filter the raw data items based on the analyst-defined dossier format, as well as add enrichments to the data.

Abstract: A proxy server receives requests from a client computer system and generates corresponding sets of database commands that are capable of fulfilling the requests when submitted to a database server. The proxy server may repeat processing associated with a particular request more than once under different operational conditions in order to improve future performance. In some examples, the proxy server submits a particular database command sequence to the database server using various operational parameters, and measures the performance of each submission to identify a particular set of operational parameters to be applied to the database server with future submissions. In another example, the proxy server determines a number of alternative command sequences that fulfill a particular request, and measures the performance of each of the alternative command sequences to determine how command sequences are generated for future requests.
