title: What search engine does mongodb use?
body: <p>I see searching on <a href="http://www.mongodb.org/dosearchsite.action?queryString=api&amp;where=DOCS" rel="nofollow">mongodb.org</a> is lightning fast. The search results are within 1 second. From what I know, mongodb doesnot support full text search. However, that does not seem to be the case while using their search. Not only do the results are fast, the site also gives additional hint when you mistype search text (like how google does).</p>
  
  <p>I am very much interested on how to achieve these results? What combination of search engine/hardware are they using?</p>
  
  <p>Thanks.</p>
