Hi Yonik,

Thanks very much for your replies!

ok. If my project actually happens I'll do my best to contribute such  
changes if they make sense to Solr.

The language switch would be per document, so one document might  
contain French and another one with the same field structure might  
contain German.

But the content of a single field would be in one language, I don't  
see a need for language switches inside the content of a field.

Having mixed languages in a single index obviously leads to some  
imprecision when searching, as the query needs to indicate which  
analyzer to use. But it still allows people to search in their own  
language and, when the query includes common words, find documents in  
other languages.
