Subject Re: Create new (sub)index from existing one

Hi Otis,

thank you for your answer. I will have a look at the link.
It can happen that search queries include several languages, and I 
thought at first, that creating a multilingual (sub-)index from a mix of 
the existing core indexes could be a way. But that is not a good 
solution, isn't it? I do have to decide on a language when posting the 
query to SOLR in order to apply the correct analyzers to the query 
input. So, it would be better to keep the languages separate and rather 
post several queries for each language, should that need arise. That is 
still fast enough, I think.

Cheers,
Chantal

criteria? (e.g. copy the main core with docs in all languages, and then delete all docs that
are not in, say, Japanese).
