Subject RE: Solr language-dependent sort

Thanks very much for quick help!

In our case we mainly need to sort a field based on language defined at run time,
but I understood that the principle is the same.

Thanks and best regards, Lisheng

Hi Lisheng,

We did something similar in Solr using a custom handler (but I think you could just build
a custom QeryParser to do this), but you could do this in your application as well, ie, get
the language and then rewrite your query to use the language specific fields. Come to think
of it, the QueryParser would probably be sufficiently general to qualify as a patch for custom
