Using Levenshtein function on each element in a tsvector?

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.

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.

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.

Is there a way to do this?
