Analysis:
both "good" and "pho" apear only once in the corpus and therefore have the same 
weight and by default we just show this order.  Adding more listings with the 
word "good" is a work around.  A possible fix for this is using some kind of 
word probability or n-gram service to weigh down words that are common.  

NOTE:
We should discuss if we want our idf to be based on the 
1. users corpus 
2. the collections of all user corpuses
3. general use of words in the english (not sure where to get this data from 
yet)
