title: Fulltext search on mysql with a 3 letter word
body: <p>I'm trying to find "the zen" string in a field containing "The Zen Circus".
  I've got a FULLTEXT index.</p>
  
  <pre><code>select url,name,
  ,   MATCH(name) AGAINST ( 'zen*' IN BOOLEAN MODE) as A
  ,   MATCH(name) AGAINST ( '"the zen*"' IN BOOLEAN MODE) as B
  ,   MATCH(name) AGAINST ('&gt;the* zen' IN BOOLEAN MODE) as C
  ,   MATCH(name) AGAINST ('thezen*' IN BOOLEAN MODE) as D
  ,   MATCH(name) AGAINST ('cir*' IN BOOLEAN MODE) as E
  ,   MATCH(name) AGAINST ('circus*' IN BOOLEAN MODE) as F
  from pages where url='thezencircus'
  </code></pre>
  
  <p>I've got this result:</p>
  
  <pre><code>url = thezencircus
  name = The Zen Circus
  A = 0   (why?)
  B = 0   (why?)
  C = 0   (why?)
  D = 0   (ok)
  E = 1   (ok)
  F = 1   (ok)
  </code></pre>
  
  <p>I've also putted ft_min_word_len = 2 in the msyql config file.</p>
  
  <p>Any idea?</p>
