title: Spacy not getting entities from text
body: <p>Have the following python code with spacy:</p>
  
  <pre><code>import spacy
  from spacy.matcher import Matcher
  
  nlp = spacy.load('en')
  
  doc = nlp("NEXT EXPEDITION ON 05/06/2015")
  print(doc.text)
  
  for ent in doc.ents:
      print(ent, ent.label_)
  </code></pre>
  
  <p>But it only results in doc.text being printed, there is no entity in doc:</p>
  
  <pre><code>doc.text = NEXT EXPEDITION ON 05/06/2015
  </code></pre>
  
  <p>Anyone can help me to figure out what am I doing wrong?</p>
