That's right. I can't think of any circumstances where you would want to consider 'hatten' and 'hätten' the same, for instance. Or Mutter and Mütter. Actually, I couldn't think of any German word where this would be the case. So when it's strictly about German, AI collations seem useless, except for catching certain foreign words and names likes Gérard/Gerard, or misspellings of Kekulé. Cheers, Paul Vinkenoog
