Searching "teh" or tihs"

[hh]

Searching is important for your project?
Would you like to ask "Did you mean the?" if user searches "teh"?

I've implemented a fuzzySearch algorithm in LiveCode script:

Now if you wish to look up "the" or "this" then fuzzySearch will find
it (among others) by searching "teh" or tihs", with a penalty score of
one only for swapping the chars.
