title: Spacy NER entities postition
body: <p>How can I get the entity position found by NER within spacy?</p>
  
  <p>From the following example:</p>
  
  <pre><code>doc = nlp('Rami Eid is studying at Stony Brook University in New York')
  print(list([(ent for ent in doc.ents])
  </code></pre>
  
  <p>it results: </p>
  
  <pre><code>['Rami Eid','Stony Brook University','New York']
  </code></pre>
  
  <p>but I need the position of each entity within the sentence, so that I can know which tokens belong to the respective entity.</p>
  
  <p>If I need to search from these results, I may have some cases where single word entities match multiple words of other entities. </p>
