title: How to create a "Next Page" link to the "non-displayed" results of mySQL search?
body: <p>I have a search engine on my webpage (PHP). So far, it would show all results on the same result page. I want to limit the number of results to 20 per page, and create a "Next Page" link...</p>
  
  <p>If I do <code>SELECT TOP 20 *  FROM ... WHERE ...</code>
  It would show only the top 20 results...</p>
  
  <p>How do I create <code>&lt;a href="..."&gt;NextPage&lt;/a&gt;</code> which would lead to results 21 to 40?
  Do I have to use AJAX?</p>
