title: Limit number suggestions display in typeahead.js
body: <p>As the title, I want to ask: "Is it possible to limit the suggestions displayed in typeahead?"</p>
  
  <p>For example, I have 3 datasets, each dataset has 10000 results (from the query). And a subject started with character <code>t</code> is about 3000 results or may be more.</p>
  
  <p>What will happened if I type <code>t</code> in the input ? 3000 result display or ... ?</p>
  
  <p>Or is there any way to force user type specific characters then display suggestions ? (Like I must type <code>tem</code>, single character like <code>t</code> will not be accpeted)</p>
