Hi all, we are currently in search of a solution for switching between different languages in the query results and keeping the possibility to perform a search in several languages in parallel. The overall aim would be a constant field name and a an additional Solr parameter "lang=XX_YY" that allows to return the results in the chosen language while searches are applied to all languages. Setting up several cores to obtain a generic field name is not an option. Does anyone know of a clean way to achieve this, particularly routing content indexed to a generic field (e.g. title) to a "background field" (e.g. title_en, title_fr) etc on the fly and retrieving it from there depending on the language chosen.
Background: So far, we have investigated the multi-language field approach offered by Trey Grainger in the code examples for "Solr in Action" (https://github.com/treygrainger/solr-in-action.git, chapter 14), an extension to the ordinary textField that allows to use a generic field name and the language is encoded at the beginning of the field content and appropriate index and query analyzers associated to dummy fields in schema.xml. If there is a way to store data in these dummy fields and additionally the lang parameter is added we might be done. Thanks a lot, best regards Johannes
