Thanks again, Ghirotondo, and thanks, Wolfgang.

Wolfgang: may I ask another question, please? My wife tells me that, in German, it is permissible to add an "e" to an un-umlaut-ed vowel rather than use an umlaut (so, eg, "schön" is equivalent to "schoen"). She frequently asks me to find books and things on the internet for her. Recently, for example, she wanted a book called O wie schön ist Panama. Would a word-search in which I entered "schoen" correctly find "schön"? (I don't know how to get the ö on my PC keyboard in Google or whatever)
