title: Viewing articles that are associated with taxonomy term A (AND) term B in Drupal 6
body: <h1>Summary:</h1>
  
  <p>I'm currently working on customizing Drupal-6 as a news portal. </p>
  
  <p>In summary, I'm trying to view posts that belong to term 5 AND term 1.</p>
  
  <p>The drupal documentation mentions that this can be achieved through the below taxonomy URL by separating the term ids with a comma (,):</p>
  
  <p><strong><a href="http://drupal-server/taxonomy/term/5,1" rel="nofollow noreferrer">http://drupal-server/taxonomy/term/5,1</a></strong></p>
  
  <p><em>(See. Using Vocabularies for Navigation: <a href="http://drupal.org/node/22273" rel="nofollow noreferrer">http://drupal.org/node/22273</a>)</em></p>
  
  <p>The above is not working as expected and is showing content with "term 5 OR term 1" instead of "term 5 AND term 1".</p>
  
  <p>Any ideas on how to fix this?</p>
  
  <h1>Problem Details:</h1>
  
  <p>I have defined two vocabularies:</p>
  
  <ol>
  <li><p><strong>"Content"</strong> vocabulary which has the terms:</p>
  
  <p>a. <strong>Events</strong></p>
  
  <p>b. <strong>News</strong></p>
  
  <p>c. <strong>Lectures</strong></p></li>
  <li><p><strong>"Academy"</strong> vocabulary:</p>
  
  <p>a. <strong>University A</strong></p>
  
  <p>b. <strong>University B</strong></p>
  
  <p>c. <strong>University C</strong></p></li>
  </ol>
  
  <p>Every time an article is posted, it is assigned a term indicating which university does it relate to, and whether it is an Event, News or Lecture.</p>
  
  <p>I'm trying to display the posts that are of type "Lecture" AND "University A".</p>
  
  <p>According to the Drupal documentation, this can be achieved using the URL:</p>
  
  <p><strong>/taxonomy/term/5,1</strong></p>
  
  <p>Assuming "University A" got assigned the term ID 5 and the "Lecture" got assigned term id 1. The documentation mentions that the comma separator (,) works as an AND operator and thus displaying only posts that relate to term 5 'and' term 1.</p>
  
  <p>Unfortunately, this is not working as expected, it is showing me the posts that relate to term 5 OR posts that relate to term 1.</p>
  
  <p>Is this a Drupal bug? Any ideas on how to force an AND? I've even tried replacing the comma with the "+" operator but with no luck (ie. /taxonomy/term/5+1).</p>
