I'm guessing Mike doesn't have (hasn't been told) the equivalent combinations to include.

If you want

æ  also = a or ae
ø also = o or oe
å also = a or aa

you probably just have to tell Mike about it.

Personally, I'm not crazy about the "single-letter" equivalents because it leads to too
many false results, but go ahead and suggest it to Mike.
