title: Fulltext search in PHP
body: <p>I want to perform fulltext search for a given phrase in a given string using PHP. </p>
  
  <p>I want this search to be:</p>
  
  <ul>
  <li>case insensitive </li>
  <li>diacritics insensitive, so for example "Žluťoučký kůň" should be matched as "Zlutoucky kun"</li>
  <li>as fast as possible</li>
  <li>independent on any third party libraries (if it is possible)</li>
  </ul>
  
  <p>Can you help me? ...I am sorry for creating new post, I've searched a lot, before I asked. However, I found only posts that concerned with PHP+MySQL search.</p>
