title: How to find the most common words using spacy?
body: <p>I'm using spacy with python and its working fine for tagging each word but I was wondering if it was possible to find the most common words in a string. Also is it possible to get the most common nouns, verbs, adverbs and so on?</p>
  
  <p>There's a count_by function included but I cant seem to get it to run in any meaningful way.</p>
