Yeah, for a general case of documents I'm not sure how accurate it would
make things, but I'm trying to index music artist names and song titles,
where I'd get things like "3 Dog Night".... or is that "Three Dog
Night"? :)

Yep, that's my problem. :) And it seems that if I could pass the normal
words into an ispell dictionary before passing them on to the en_stem
dictionary, I'd get spell checking for free. Unless there's a better way
to give "did you mean: <your search spelled correctly>?" results....?
I know doing this would increase the size of the generated ts_vector,
but for my case, where what I'm indexing is generally only a few words
anyway, that's not an issue. As it is, I'm already going to get rid of
the stop words file, so that I can actually find things like "The Who."
How hard do you think it would be to change up the behavior to make this
happen? I

I want to be able to recognize symbols, such as the degree (°) and
vulgar half (½) symbols.
