    |  | Use the form below to search for
        documents in this web containing specific words or combinations of words. The text search
        engine will display a weighted list of matching documents, with better matches shown
        first. Each list item is a link to a matching document; if the document has a title it
        will be shown, otherwise only the document's file name is displayed. A brief explanation of the query language is
        available, along with examples. 
 The text search engine
        allows queries to be formed from arbitrary Boolean expressions containing the keywords
        AND, OR, and NOT, and grouped with parentheses. For example: 
          
            information
              retrievalfinds documents containing
              'information' or 'retrieval'
