title: storing an array in mongodb
body: <p>I'm new to mongodb 3.2 and I'm wondering what the accepted method to store an array. </p>
  
  <p>I have a safe words array that just contains... words.</p>
  
  <p>I want to store it in mongodb for a fast comparison of a queried word.</p>
  
  <p>should I just create a document, and add to it objects with one property called 'word' that contains a word?</p>
  
  <p>should I create a document with one object that contains the property words with an array of words?</p>
  
  <p>maybe something else?</p>
  
  <p>any ideas?</p>
