mysql: efficient way for postfix-search (like '%text' aka. prefix wildcard)?

Question

MySQL won't use an index when your value starts with a wildcard character.

Storing a second column in reverse order is a defensible approach. It will fail on a suffix, though.

If you know the compounded words, you can pre-compute "valuable to know" matches and store them in another table. I think that's unlikely to work well for a German dictionary, but you might know something I don't.
