Hello, I'm new to Elastic. I would like to develop a .Net application that will use Elastic. I had a question about the research part. I have several types of documents with each specific metadata. Would it be possible to create search fields based on metadata. Example: Document type: _Invoice_, Metadata: _Customer, amount, Date_. Create search fields: Customer, amount and Date. ---

Hey, I'm not super sure about the question here. Elasticsearch itself does not know about data or metadata. You can specify fields that you can search. Maybe you can add some more context what you expect from that metadata compared to regular fields in order to fill the gaps. Thank you! --Alex ---
