Latest Patents

One of his latest patents is titled "Hybrid search for parent-child related documents." This patent discloses techniques for implementing a hybrid search for documents that have a parent-child relationship. The method involves building a base index using a first table of parent documents and a second table of child documents. The base index stores document identifiers of both parent and child documents in contiguous document blocks. Each block contains the document identifier of a parent document along with the identifiers of its related child documents in a sorted order. After building the base index, the method updates a live index to include identifiers of additional parent and child documents. It then computes a hybrid set of search results for a search query using both the base and live indexes.

Another significant patent is "Differential indexing for fast database search." This patent presents methods, systems, and computer programs aimed at improving search speed and quality through differential indexing. The method includes building a first index for a database based on normalized words from input data. It also involves creating a second index for tokens that were eliminated from the first index during normalization. The process includes receiving a raw query for a database search and generating a search query based on the tokens. The search query combines searches of both indexes, and results are returned for display.
