A multi-lingual indexing and search system is presented that performs tokenization and stemming in a manner which is independent of whether index entries and search terms appear as words in a dictionary. The system includes a tokenizer that separates a string of text into individual word tokens, and eliminates predetermined types of tokens from further processing. The system also includes a stemmer that reduces words to grammatical stems by removing known word-endings associated with the various languages to be supported. The stemmer removes known word endings from the word tokens without any effort to guarantee that the remaining stem is contained in a dictionary. In an embodiment, the stemmer only removes those word endings which are associated with nouns. The system further includes an indexer that stores the stems in an index.

Multi-language document search and retrieval system

A multi-lingual indexing and search system performs tokenization and stemming in a manner which is independent of whether index entries and search terms appear as words in a dictionary. During the tokenization phase of the process, a string of text is separated into individual word tokens, and predetermined types of tokens are eliminated from further processing. The stemming phase of the process reduces words to grammatical stems by removing known word-endings associated with the various languages to be supported. Known word endings are removed from the word tokens without any effort to guarantee that the remaining stem is contained in a dictionary. In a preferred implementation, the stemming process is only applied to nouns.

A method and apparatus for maintaining information in a network of computer systems and for controlling the display of searchable information. The apparatus includes a first processor having a first display device and being coupled to an information storage device having information stored in at least one information source, where the first processor is coupled to a network. An input device is coupled to the first processor, where the input device is for selecting the information source to provide a selected information source which is to be unavailable for searching. A second processor having a second display device is coupled to the network to communicate with the first processor. The second display device is for displaying an indicia of information source, where the second display device displayed the indicia of the information source when the information source has not been selected by the input device. When the input device has selected the information source the indicia at some point in time after the information source has been selected is no longer displayed on the second display device. The method includes displaying on a first display device to a first indicia which corresponds to an information source stored on an information storage device. The method further includes displaying on the second display device a second indicia corresponding to the information source, this second indicia being displayed when the information source is not selected by the input device. When the information source is selected, at some time after selection, the second indicia is longer displayed on the second display device.
