Spell check collation

Solr 4.6

Current settings for my handler:

      <str name="name">default</str>
      <str name="field">spell</str>

    </lst>
  </searchComponent>

I'm querying:
h G's collision centre

hoping for a spell check suggestion of:
J G's collision centre

But there are no suggestions. Is there is term length limitation to 
spellchecking?

Thanks,

Corey
