So the problem you have is where to pull recommendations from. For my
own needs, I use a spell checker to do the "did you mean", which means
my data source is external, and thus I never hit the index twice.

As you seem to want to correlate the user's input with *existing*
entries in your index, then I still think you'll need to hit the index
twice, one using the analyzers you'd normally use, and another with a
fuzzy query.

To help scaling things, you could have 2 indexes. But that's another story.
