To start off, I'll have to admit I've never tried something like this, but I think I can direct you a bit. If you have a Hashtable (or even a Dictionary), they store values on a 1:1 basis (i.e. one key, one value).

So, the only way to approach this problem as you've stated it without resorting to a different data structure that might be more appropriate, you would have to iterate over each key in the table comparing it with your 'fuzzy' compare method. You could also try seeding the hashtable with possible values to map the multiple keys to the same value, but this would require a limited set of valid values it would map to.

Otherwise, you'll need to look at different data structure that would be more suited to your needs.
