  • Using text search engine for parametric search
    Patent number: 8332422
    Abstract: A method, system, and computer program for enabling parametric searches on source data using text search engine. The invention is generally divided into a build-time process and a run-time process. During the build-time process, a crawler extracts data units from source data. A data translator then translates data units into keyword parametric entries that are submitted to the text search engine. During the run-time process, a query translator translates parametric search queries into keyword search entries. A metatag refiner then filters intermediate search results from the search engine based on the parametric search query.
    Type: Grant
