Improving results with Fuzziness on


I'm trying to improve my search results with the fuzziness parameter, however, I have a very language specific issue:

In Spanish, many female names and words just add an "a" at the end of the male version of the word, when I search for a female name like "Daniela" with fuzziness set to auto or 1, I get returned "Daniel" as a result, I'd have to type "Danielaa" for the search to match "Daniela"

Any help on this issue?
