Suppose you have a collection of games where the same name is spelt or recorded differently in a database, e.g. “Mueller” and “Müller”.  If you search for Müller’s games as White by entering “M” under the first and last names (with “Ignore colours” active), then only the games where the player was recorded as “Mueller” are returned, or in which Black also had a name beginning with M.

 

This is due to the way that the program has been implemented - it operates on the assumption that players’ names can only be composed of letters from A-Z and does not include other characters, such as umlauts other diacritics.

 

Solution: Use the * wildcard and enter “M*” instead of “M”
