<p>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 <a HREF="#querylang">explanation</a> of the query language is 
available, along with examples.</p>

<h2><a NAME="querylang">Query Language</a></h2> 
 
<p>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:</p> 
 
<blockquote> 
    <dl> 
        <dt><strong><tt>information retrieval</tt></strong></dt> 
        <dd>finds documents containing 'information' or 
            'retrieval'<br> 
            <br> 
        </dd> 
        <dt><strong><tt>information or retrieval</tt></strong></dt> 
        <dd>same as above<br> 
            <br> 
        </dd> 
        <dt><strong><tt>information and retrieval</tt></strong></dt>
        <dd>finds documents containing both 'information' and 
            'retrieval'<br> 
            <br> 
        </dd> 
        <dt><strong><tt>information not retrieval</tt></strong></dt> 
        <dd>finds documents containing 'information' but not 
            'retrieval'<br> 
            <br> 
        </dd> 
        <dt><strong><tt>(information not retrieval) and WAIS</tt></strong></dt> 
        <dd>finds documents containing 'WAIS', plus 'information'
            but not 'retrieval'<br> 
            <br> 
        </dd> 
        <dt><strong><tt>web*</tt></strong></dt> 
        <dd>finds documents containing words starting with 'web'<br> 
            <br>
