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
