     *

     * Update from jwage: I am not sure if their is any other better solution for this. It may be the correct

     * solution to disable the indexBy settings for tables when exporting data fixtures. Maybe a better idea

     * would be to extract this functionality to a pair of functions to enable/disable the index by settings

     * so simply turn them on and off when they need to query for the translations standalone and don't need

     * it to be indexed by the lang.
