After the recent discussion on LaTeX style accents, I have been reminded of this old discussion at tea regarding the appropriate spelling convention for some German names, such as Kähler. At the time, we saw that Google search (US, Canada, UK) for Kahler also matched Kähler and Kaehler but not as much the other way around. Our new MathOverflow search engine (which is still much better than the old one) does not associate any of the three spellings.
Current search counts are:
- Kahler - 473 local hits - 1870 google.com (US) hits
- Kähler - 280 local hits - 1030 google.com (US) hits
- Kaehler - 126 local hits - 577 google.com (US) hits
(Note: Google search
site:mathoverflow.net kahler -kähler -kaehler and variants can be used estimate the overlap.)
Should there be a preferred spelling convention to facilitate searches? Should the MathOverflow search engine try harder to match alternate spellings?
