Abstract: Methods and systems to build and utilize a search infrastructure are described. The system generates index information components in real-time based on a database that is time-stamped. The system updates index information at a plurality of query node servers based on the index information components. A query engine receives a search query from a client machine and identifies search results based on the query and the index information. The system communicates the search results, over the network, to the client machine.

Abstract: Methods and systems to build and utilize a search infrastructure are described. The system generates, by a first indexing subsystem, full indexes of data and sends the full indexes to a plurality of query node servers via a distribution system. The system generates, mini-indexes associated with the full indexes and sends the mini-indexes to the plurality of query node servers. The system causes the plurality of query nodes to update indexing information based on the full indexes and the mini-indexes.

Abstract: Methods and systems to build and utilize a search infrastructure are described. The system generates index information, including document updates and indexes. The system receives event notifications as the document updates are received and accumulates the index information until published. A query engine receives a search query from a client machine and identifies search results based on the query and the index information. The system communicates the search results, over the network, to the client machine.

Abstract: In various example embodiments, a system and method for versioning data in an unstructured data store are presented. The method includes generating a first record in the unstructured data store based on a version of a second record in the unstructured data store. The method further includes initializing a parent version identifier of the first record based on the version of the second record. The method further includes comparing the parent version identifier of the first record to a version identifier of the second record. The method further includes determining whether the first record is consistent based on the comparison.

Abstract: Systems and methods to process a query with a unified storage interface are described. The system receives a query from a client machine and generates a query expression tree based on the query expression. The system generates a cursor expression tree based on the query expression tree. The system executes a plurality of software components in the cursor expression tree to retrieve data from a first storage device. The plurality of software components comprise a first software component that is utilized to retrieve data irrespective of a plurality of storage devices and a second software component that is utilized to retrieve data from a first storage device. Finally, the system communicates search results to the client machine, the search results include at least a portion of the data.
