I'm using ES 5.1.2 and NEST 5.x, I'm trying add an ingest pipeline similar to the example given below.
In my implementation I have a Base64DocumentContent field which has the base64 string. I want the extracted "attachment.content" to be copied to "Content" field.
I have the following NEST query
_elasticClient.PutPipeline(_documentAttachmentPipeline, p => p .Description("Document attachment pipeline") .Processors(pr => pr .Attachment<T>(doc => doc .Field(f => f.Base64DocumentContent)) .Set<T>(set => set .Field(f => f.Content).Value("attachment.content"))));
Instead of setting the attachment.content value it is assigning the string "attachment.content". How do I set "attachment.content" extracted value to Content field.
