International indexing/searching is available for most scripts/languages (Western, Middle Eastern and Eastern languages)- but this can be further enhanced using a 'Language Pack'. If no language pack is used, there are no special configuration settings required, the engine will automatically index/search most languages.
Please download the language packs here.
To install a language, unzip the ZIP file, find the appropriate language folder and copy the contents into the index directory that should use the language.
By default diacritics are handled like their ASCII counterpart, for example 'é' is treated the same as 'e'. To have diacritics be treated distinctly, set Configuration.IgnoreDiacritics = false.
