Interesting. I'm currently writing a spell-checker and it looks like I'm doing things a bit differently. I started with a list of about 134k words I got off the internet somewhere and converted them to lower-case. When I check the spelling, I check the lower-case version of the word submitted.

To tweak the speed and completeness, I'm planning to have it run through all existing messages and track the number of hits for each word, and track the number of misses in a separate table. Then any word that was never hit (in 250k messages) will get removed from the dictionary and any valid words that were frequent "misses" will get added.

Once in production, I'll have a maintenance screen that'll show me "misses" that need to be added.

I'd have it do the additions automatically by setting a number of times a word can be "missed" before it's automatically added to the word list, but if there's anything I know, I know the people I'm dealing with. And can just see people repeatedly using a typo just to get it added to the dictionary. <g> Heck, I know it's the first thing I'd do.

What I've currently got written isn't going to work for production (takes about 2 seconds to spell-check a typically long-winded message of mine on my home equipment), so once I have it done, John will use it as a model to write something a lot faster that never makes calls to the SQL backend.
