Methods, systems, and programming for retrieving content items for a search are described herein. In a non-limiting embodiment, a query including a plurality of terms may be received. For each of the plurality of terms, a posting list of one or more content items may be obtained. The posting list may include a ranked list of term scores corresponding to the one or more content items, each of the term scores being indicative of a level of relevance of a corresponding content item to a term associated with the posting list. A list of relevant content items for the query may be determined based on the term scores in each posting list for the one or more content items identified with respect to each term. At least one of the relevant content items may be provided as a response to the query.

System and method for top-k searching using parallel processing

Methods, systems, and programming for updating a search index are described herein. In a non-limiting embodiment, event data representing actions performed on a plurality of content items managed via the search index may be obtained. The event data may be filtered based on pre-determined criteria to generate updated event data, where the updated event data represents relevant actions performed on at least one of the plurality of content items and are associated with the search index. An updated search index based on the updated event data may then be generated.

Technologies for enhancing work scheduling of a big data framework. The technologies can include generating, in a database, configurable namespaces to be used by a work scheduling enhancement application to group together tasks of one or more big data clusters. The namespaces can be hierarchical. The technologies can also include linking in the database, by the application, related tasks with respective namespaces to categorize and group together the related tasks. The technologies can also include configuring, by the application, a display scheme for displaying error handling and root cause analysis of tasks of the one or more big data clusters. The technologies can also include generating or rendering, by the application, a GUI having a navigable hierarchal view for displaying the namespaces. The generation or rendering of the GUI can be based partially on the display scheme.

Graphical management of big data pipelines

Systems and methods for indexing content in a personal search system are disclosed. In one embodiment, the method comprises receiving a content item from a data source; extracting, from the content item, at least one document appearing in the content item, the at least one document including a first timestamp; storing the document in a content index; retrieving an event associated with the document from an event index, the event including a second timestamp and one or more attributes; generating an updated document based on the one or more attributes, the updated document including the second timestamp and the one or more attributes; and replacing the document stored in the content index with the updated document if the second timestamp is later than the first timestamp.

Systems, devices, and methods for content indexing and querying in a search system

The present teaching relates to concurrent database operation. In one example, a plurality of requests which includes a scan request to obtain first data associated with a plurality of first keys stored in a database is received concurrently. A global version number is updated upon receipt of the scan request. The first data associated with the plurality of first keys is obtained based on the updated global version number. The first data is provided in response to the scan request.

Method and system for concurrent database operation

Methods, systems, and programming for accessing data are described herein. In a non-limiting embodiment, a request associated with a key may be received. A memory chunk in a first memory site associated with the key may be located. An entry in the memory chunk corresponding to the key may be determined. A first pointer to the key corresponding to a first location of the key within a buffer at a second memory site may be obtained from the entry. The key stored at the first location may be retrieved from the buffer at the second memory site.
