Locales Filters API

Hey! I have an issue here:

So when I want to fetch filtered collection data with a certain local it still filters fields default local…and it works if you add _local (_ru, _es) to the field name

So rn I try ...?local=ru&filter={Title:{$regex: 'Значение',$options: "i"}} and it gives me nothing, but if I do ...?local=ru&filter={Title_ru:{$regex: 'Значение',$options: "i"}} it gives me what i need.

It is really messy, so I would be cool if defining locale makes filter option search for local field.

Could you explain it more??
