I know this is possible with Rest but would like to know if there is any way to upload Documents that are valid JSON only without the need to deserialize them and provide an object?
This is purely a performance optimization. Our SQL query returns the object as JSON and would prefer not to have to deserialize it in .Net consuming resources to be able to upload to Azure Search.
After thinking through using a custom JsonConverter scenario where I store a string and retrieve it, I have dismissed that option as probably not worth while.
No, the SDK does not support this scenario. You'd be better off writing a simple client to send your JSON to the REST API directly.
