Have you looked at edismax and the 'qf' fields parameter? It allows you to define the fields to search. Also, you can define those parameters in solrconfig.xml and not have to send them down the wire.
Finally, you can define several different request handlers (e.g. /ensearch, /frsearch) and have each of them use different 'qf' values, possibly with 'fl' field also defined and with field name aliasing from language-specific to generic names.
