title: is there a length limit to group_concat or another reason why it would not work on a text field
body: <p>First, here is the query:</p>
  
  <pre><code>SELECT GROUP_CONCAT(title) title, GROUP_CONCAT(description) description,
  skill_id, count(*)
  
  FROM jobs j
  INNER JOIN job_feed_details d
  ON j.id = d.job_id
  JOIN jobs_skills js
  ON j.id = js.job_id
      WHERE moderated = 1
      group by skill_id
  </code></pre>
  
  <p>Everything works as expected except the description field only returns one result, instead of a concatenation of all results. I suspect this is because the description is a <code>text</code> field, but I cannot find anything about why concatenation would not work with a text field.</p>
  
  <p>Anyone know why this would not work?</p>
