Product Search Fuzziness

Different matching rules are applied depending on the Search Fuzziness level that you can set under Search Settings > General. There is a Default fuzziness level but no 'optimal' one as it depends on how your data is structured as well as on how fuzzy or strict you'd like your search results to be.
