title: Using Levenshtein function on each element in a tsvector?
body: <p>I'm trying to create a fuzzy search using Postgres and have been using django-watson as a base search engine to work off of.</p>
  
  <p>I have a field called search_tsv that its a tsvector containing all the field values of the model that I want to search on.</p>
  
  <p>I was wanting to use the Levenshtein function, which does exactly what I want on a text field. However, I dont really know how to run it on each individual element of the tsvector.</p>
  
  <p>Is there a way to do this?</p>
