<diacritics_sensitive> element. This element determines whether diacritical marks such as accents should be ignored or applied by the search system when expanding a query with terms from the thesaurus. By default, the <diacritics_sensitive> element is set to zero to ignore diacritical marks.<diacritics_sensitive> element is not available. Instead, diacritical marks are always respected when matching query terms with terms in the thesaurus.<munchen> is not matched with the query term<münchen>.| Feature | FAST Search web crawler | SharePoint 2013 crawler | Migration path |
