indexDir looks like the path to the spellchecker index. But there is also 
spellcheckInexDir. Is there a functonal difference?

Good point, I fix that.

Is that doable?

Of course it is, I just didn't know why you would want to.  I get the file 
based need, b/c that is where you can put overrides, but I just don't get the 
need for another index, since wouldn't it have to have the same frequencies, 
etc. to return appropriate suggestions?

> Expose the Lucene contrib SpellChecker as a Search Component. Provide the 
> following features:
> * Allow creating a spell index on a given field and make it possible to have 
> multiple spell indices -- one for each field
> * Give suggestions on a per-field basis
> * Given a multi-word query, give only one consistent suggestion
> * Process the query with the same analyzer specified for the source field and 
> process each token separately
> * Allow the user to specify minimum length for a token (optional)
> Consistency criteria for a multi-word query can consist of the following:
> * Preserve the correct words in the original query as it is
> * Never give duplicate words in a suggestion
