*
* 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.
