title: How to find beginswith word in a string using NSPredicate?
body: <p>I am searching for a solution on how to format NSPredicate to search correct word in a string of text.
  Currently I am using this code:</p>
  
  <pre><code>NSPredicate *predicate = [NSPredicate predicateWithFormat:
                            @"(content CONTAINS[c] %@)", word];
  </code></pre>
  
  <p>but it returns wrong resuls if the word is short, for example:
  if the word is 'ail' it will return all strings with words which include this 3 letters.. But I don't need such abstract search, so how to search words 'beginswith' my word in a string?</p>
