Abstract
A method and apparatus for processing user-submitted search information to permit a database to be searched regardless of the format and language of the user-submitted information. The user-submitted information is first categorized into one or more categories, where each category is a type of information such as a date, a proper name or a place. For each category pertaining to the user-submitted information, the search is refined by comparing the user-submitted information to a feature table containing specific data types corresponding to each category. From the results of any affirmative comparison with the feature table, a starting location within a corresponding search table is retrieved. The search is further refined by comparing the user-submitted information to the entries of the search table beginning at the starting location. From the results of any affirmative comparison with the search table entries a database address is obtained which is used to obtain a database entry sought after by the user.
