title: Sphinx sentence like query
body: <p><br>
  my task is to find a similar sentence in database collection.</p>
  
  <p>Could you advise me which query type to use?</p>
  
  <p>Sample:
  <strong>Search:</strong> <em>Welcome to the first sample code.</em></p>
  
  <p>And let say the following sentences are fine for my query:</p>
  
  <p><strong>Dbase:</strong></p>
  
  <p>...</p>
  
  <p>Welcome in first movie ...</p>
  
  <p>This is first sample code ...</p>
  
  <p>Welcome!
  ...</p>
  
  <p>Thanks</p>
