I have a little "German" Problem, hope someone knows a solution:
In Germany we have the letters ä ö and ü very often in our Keywords. But it is possible to spell an ö like oe f.e. It depends on the authors ideas 
So if someone writes a word like "Oel" into the seach-inputfield (which means oil), than you can't find it by seaching for "Öl" (same in the other direction, looking for "Oel" when there is "Öl" in text). Is there a possibility to fix that issue by the "did you mean..." function, or maybe another function?
