The search has to bring related results to the keyword, not only results that has it. A basic feature to do that is to ignore accentuation

A patch for "Splitter.c" i'm using with french words to ignore accentuation ! (see the function "sans_accent" and add yours portuguese caracters) Jean-Louis BERLIET

Your patch to Splitter.c contains a mapping for letters that are also used as umlaut characters in German which isn't correct. You would have to map the German "a to ae, "o to oe, "u to ue, and finally the sz ligature to ss. Greetings Eric
