title: Mysql similar text search
body: <p>I have a mysql table like below-</p>
  
  <pre><code>------------
  keyword_text
  ------------
  Lego kit for kids
  Lego kit only for kids
  Lego kit kids
  
  +more different text entry
  </code></pre>
  
  <p>As you can see, the <strong>keyword_text</strong> in above example are all similar. I want to find all those match for any of the above keywords. For example if I search for <strong><em>Lego kit only for kids</em></strong> , it will return me all of those 3 keyword_text. </p>
  
  <pre><code>Input:
  Lego kit only for kids
  
  Output:
  Lego kit for kids
  Lego kit only for kids
  Lego kit kids
  
  OR 
  
  mysql resource to use with mysql_fetch_assoc
  </code></pre>
  
  <p>The table has approximately 1M entry and <strong>full text index</strong> is added to <strong>keyword_text</strong>. Is there any mysql query to do that or any similar way to do it quickly using PHP?</p>
  
  <p>Thanks for help</p>
