Solr 6.1 :: language specific analysis

Hello,

I wonder if solr offers a feature (class) to handle different orthogaphy versions?
For the German language for example ... in order to find the same documents when searching after "Foto" or "Photo".

I appreachiate any help!

Rainer

BeiderMorse supports these phonetics variations like Foto / Photo and have
support for many languages including German.  Please see
https://cwiki.apache.org/confluence/display/solr/Phonetic+Matching

Thanks,
Susheel

ICU normalization (ICUFoldingFilterFactory) will at least handle "ß" -> "ss" (IIRC) and some other language-general variants that might get you close.  There are, of course, language specific analyzers (https://wiki.apache.org/solr/LanguageAnalysis#German) , but I don't think they'll get you Foto->photo.  

You might experiment with DoubleMetaphone encoding (DoubleMetaphoneFilterFactory) or, worst case, back off to synonym lists (SynonymFilterFactory) for your domain.
