FieldData Data accessibility

[jamahalwin]

When performing a search or query operation on a collection, it is possible to specify the output fields to retrieve. However, the retrieved data cannot be directly manipulated. For a RAG applications, it would be beneficial to enable access to a text field that has been associated with a given vector.

Is this by design or is this being worked on?

The FieldData can be downcast to a FieldData<TData> to access the data.
