title: Innodb: Can't find FULLTEXT index matching the column list when queried more than 1 columns
body: <p>I'm trying to run a very simple query on my MySQL INNODB table:</p>
  
  <pre><code>SELECT * 
  FROM items 
  WHERE MATCH (item_title,item_description) AGAINST ('dog')
  </code></pre>
  
  <p>Both column <code>item_title</code> and <code>item_description</code> have a <code>FULLTEXT</code> index.</p>
  
  <p>I keep getting this error: </p>
  
  <blockquote>
    <p>Can't find FULLTEXT index matching the column list</p>
  </blockquote>
  
  <p><strong>My issue:</strong> when I query <em>just</em> <code>item_title</code> or <em>just</em> <code>item_description</code> then it works fine. But when I do both at once in 1 query, as shown above, I get that error.</p>
  
  <p>Any idea what is wrong?</p>
