I'd like to set stemming language on a per-user basis in Django Haystack with ElasticSearch as backend.
In our Django model, we have image objects, that contain comma-separated tag charfield for English, Spanish, German, ...: tags_en, tags_es, tags_de, etc.
Spanish users should be searching only in tags_es and queries should be stemmed also in Spanish.
I couldn't find anything about such a feature and I don't mind tempering inside Haystack's ElasticSearch-backend. Can you point me into the right direction? If there's a solution for Haystack with Solr, that's okay as well.
