Also I have another question we are trying to enable multi language search for our platform but when user adds a new language we need to update all documents with new search attribute such as `{"search": "Default Product Name", "search_de": "Product name in deutsch", ...}`but we want to use default search attribute if there is no search_de exists in document instead, in this way we don’t need to update all documents do you have a suggestion to resolve this issue or should we have to update all documents?

Is it the case that you want to fallback to a generic (maybe english) field when a language specific field does not exist in a document?

yes to prevent that we are automatically adding new search_de field to all documents with same default search value then user updates search_de for specific documents if he wants to

This will require some kind of special syntax during query time, which can do something like

use this field if it exists or use another default field

like

query_by=searche_de|search,brand

right?

Right. Can you please add your use case as a comment to the github issue above? We will have to arrive at a syntax that can cover all these cases.

Of course adding it 👍
