Creating a Collection in Typesense Cloud with Firebase Extension

TLDR Lukas asked about creating collections in Typesense with objects, which Kishore Nallan informed is not supported. Kishore Nallan suggested flattening the fields and reassured that an array of strings can be used for tagging purposes.

Hey all,

I'm trying to create a collection in typesense cloud with firebase extension. Just wanted to know are objects not supported?

calories = {
  calories: 200,
  protein: 30,
  carbs: 10
}

Request failed with HTTP code 400 | Server said: Type of field `calories` is invalid.

Yes, Typesense does not support indexing nested objects yet.

The fields need to be "flattened" out.

Yeah, I've seen once it's flattened it works.

We've a feature request open for it here (https://github.com/typesense/typesense/issues/227). It's a bit of an involved change, but we certainly think it is a good feature to support in future.

Thanks for that! Just a quick one, so let's say I want to implement tags for searching.
Would I have to do it like this: isVegan: true instead of obviously storing in array.

Array of strings is fine. What we don't support is a dictionary. So you can't index a dictionary like person: {name: "foo", age: 20} -- instead you need to have 2 fields "person.name" and "person.age" separately.
