I think that this is a point where the requirements for the developers can be a little too much. See it this way, we are only indexing a string. It shouldn't be necessary to implement a hash code for converting them to numbers. Besides, most of us, or at least me, are not experts in the hashing techniques and for sure we can't be certain that the hash is correct or that don't clash.
If you want to use a big, fat, e-mail address as a "unique identifier", you will be better served to use most of a 64 or 128-bit key-space than a small percentage of a 400-bit key-space. Using only the alpha range:
(MaSearchStringIndex attribute: #email) keySize: 128; beAlpha; yourself
This line it is perfect for the wiki page, instead of the current one, because it will give the expected results most of the time. Of course the note about the limit cases should be present.
My Bad,
I threw that code together in a rushed weekend a long time ago and thought no more of it, it worked, but then I only had 3 records!
Please do feel free to update the wiki page with improvements
Done,
Miguel Cobá
