Latest Patents
Rasscevskis's latest patents focus on advanced indexing systems. One of his patents describes a hybrid-sharded index that includes document-sharded posting lists and term-sharded posting lists. This patent outlines systems and methods for updating a hybrid-sharded index. For instance, a method may involve receiving updates to the hybrid-sharded index and generating replacement posting lists at a first leaf node, along with change information for a respective second leaf node. The method also details how to divide the replacement posting lists into portions and send them to respective leaf nodes. At a particular leaf node, the method includes merging a received portion into an updated posting list portion and swapping it into memory. During this process, change information and the updated posting list portion are utilized to respond to queries with an older version of the hybrid-sharded index.
Another patent by Rasscevskis also focuses on a hybrid-sharded index, emphasizing the use of a distributed hybrid-sharded index. This method includes receiving a query at a root node and determining if the first term is term-sharded. The method further explains how to retrieve a term-sharded posting list for the first term and determine a second leaf node that stores a document-sharded posting list for the second term. The process involves sending the second term and a subset of documents from the term-sharded posting list to the second leaf node, ultimately generating a search result based on the response received.
