Ferret Only Searching on Two Fields?

I have a model with about ten fields indexed. When I do simple one word
search, ferret is only searching on the first two fields. I have to use
prefixes to search the other fields. What am I doing wrong?

For instance, this:

dragon

Gets turned into this (according to my ferret_index.log):

name:dragon text:dragon

I want it to search for dragon on all ten fields.
