This example searches the directory for objects and abandons the search before it completes. 
    try {
        // Specify the attributes to match
        // Ask for objects that have attribute "sn" == Geisel and the "mail" attribute
        Attributes matchAttrs = new BasicAttributes(true); // ignore case
        matchAttrs.put(new BasicAttribute("sn", "Geisel"));
        matchAttrs.put(new BasicAttribute("mail"));
    
        // Search for objects with those matching attributes
        NamingEnumeration enum = ctx.search("ou=People", matchAttrs);
    
        if (enum.hasMore()) {
            SearchResult entry = (SearchResult)enum.next();
    
            // Abandon rest of results
            enum.close();
        }
    } catch (NamingException e) {
    }
