title: How to get results using customize order by query with sparql
body: <p>If there are some data in .nt data file like : </p>
  
  <pre><code>&lt;ted&gt; &lt;pre&gt; &lt;a&gt;.
  &lt;alice&gt; &lt;pre&gt; &lt;b&gt;.
  &lt;ella&gt; &lt;pre&gt; &lt;c&gt;.
  &lt;hens&gt; &lt;pre&gt; &lt;d&gt;.
  &lt;lee&gt; &lt;ppp&gt; &lt;other&gt;.
  </code></pre>
  
  <p>I want to order the data by <code>&lt;pre&gt;</code> in customize. </p>
  
  <p>The SPARQL query is :</p>
  
  <pre><code>//customize order by
  select distinct ?s ?o where {
  values (?o ?o_){(&lt;a&gt; 1)(&lt;b&gt; 2)}{?s &lt;pre&gt; ?o}
  } order by ?o_` 
  </code></pre>
  
  <p>The result is </p>
  
  <pre><code>&lt;ted&gt; &lt;pre&gt; &lt;a&gt;
  &lt;alice&gt; &lt;pre&gt; &lt;b&gt;
  </code></pre>
  
  <p>I want to get all data andI ask if there has wildcard for other data.</p>
  
  <pre><code>//(&lt;*&gt; 3) is pseudocode
  select distinct ?s ?o where {
  values (?o ?o_){(&lt;a&gt; 1)(&lt;b&gt; 2)(&lt;*&gt; 3)}{?s &lt;pre&gt; ?o}
  } order by ?o_`  
  </code></pre>
  
  <p>Then I can get the data result :</p>
  
  <pre><code>&lt;ted&gt; &lt;pre&gt; &lt;a&gt;
  &lt;alice&gt; &lt;pre&gt; &lt;b&gt;
  &lt;ella&gt; &lt;pre&gt; &lt;c&gt;
  &lt;hens&gt; &lt;pre&gt; &lt;d&gt;
  &lt;lee&gt; &lt;ppp&gt; &lt;other&gt;
  </code></pre>
