This is my Firestore structure:
Products(root) -> product(document) -> prices(subCollection)
The prices collection is in each product document.
According to Algolia Firebase extension instructions, this is how to define the field for indexing. But there is no example for sub-collection.
The current field that I have set for indexing are in the product(document) but I also want to select certain fields inside the prices(subCollection).
Is there a way to tell the Algolia Firebase extension to index certain field inside the prices sub-collection as well?
