Django-Haystack + Whoosh - Are misspelling suggestions possible?

I'm using Whoosh and Django-Haystack. I would like to make use of query suggestions for when users mistype words.

e.g. Maybe you meant "unicorn"

Is it necessary to use another search engine? Or can I successfully achieve this with Whoo开发者_如何学编程sh?

Haystack lets you enable spelling suggestions, and that does work with Whoosh.

I have no experience with Whoosh, but comparing edit distance and rolling your own wouldn't be too complex, if necessary.
