Checking Dictionary

So, I wanted to do a wordfeud mockup (nothing fancy) and what I don't understand is how I'm going to check all words, I have a dictionary with 350k words, and that is simply too big for computercraft from what I know.
Has anyone tried something involving a dictionary before? I'd like to see how that was accomplished…
Searching the forum gives me one result, the idea exchange thread, but that's just an idea.

If I were actually to make something similar to wordfeud, how would I go about checking the words? (You can't trust that people are honest =P)

https://raw.githubus...aster/words.txt for the dictionary…

Personally, I'd offload this to something like this.

Huh, maybe that would work! Thanks! ;)/>
Also, if anyone got ideas, feel free to make something like wordfeud. what I'm making is just proof of concept.
Thanks again!
