Are you detecting the language, and based on that, indexing to one of mytext_de, mytext_cjk, etc., or does each field have mixed languages? If the former, why could you not also detect the language at query time (or, have separate query sources for users of different languages), and query the appropriate field based on the known language to be searched? > Therefore I was wondering if there was a way to copy fields at search > time, so I can have my mytext query in a single field and have it > copied to mytext_de, mytext_cjk etc. Something like: > > <copyQueryField source="mytext" dest="mytext_de" /> > <copyQueryField source="mytext" dest="mytext_cjk" /> > ... > > If this is not currently possible, could someone give me some pointers > for hacking Solr to support it?
