Hello,

I've searched through the docs and existing examples and I can't seem to find the implementation for scalar indexes. I tried using create_index on a scalar field, but it failed with Error: Schema(NotVectorField("field_name")), which makes sense since it appears that IndexParams only has fields for embedding indexes.

Does the rust SDK currently have indexing for scalars? If not, is there plan to add that eventually?

Thanks! Brandon
