  Body: Tutorial: Similarity Queries
  https://radimrehurek.com/gensim/auto_examples/core/run_similarity_queries.html#sphx-glr-auto-examples-core-run-similarity-queries-py
  
  Notice the document order in the tutorial:
  ```
  documents = [
      "Human machine interface for lab abc computer applications",
      "A survey of user opinion of computer system response time",
      "The EPS user interface management system",
      "System and human system engineering testing of EPS",
  ```
  
  Current snippet in the tutorial prints text in the original documents order, not the actual associated text. 
  ```
  sims = sorted(enumerate(sims), key=lambda item: -item[1])
  for i, s in enumerate(sims):
      print(s, documents[i])
  
  Out:
  (2, 0.9984453) Human machine interface for lab abc computer applications
  (0, 0.998093) A survey of user opinion of computer system response time
  (3, 0.9865886) The EPS user interface management system
  (1, 0.93748635) System and human system engineering testing of EPS
  ```
  
  The code should be
  ```
  sims = sorted(enumerate(sims), key=lambda item: -item[1])
  for s in sims:
      print(s, documents[s[0]])
  
  Out:
  (2, 0.9984453) The EPS user interface management system
  (0, 0.998093) Human machine interface for lab abc computer applications
  (3, 0.9865886) System and human system engineering testing of EPS
  (1, 0.93748635) A survey of user opinion of computer system response time
