How to index azure blob custom metadata fields to Azure search

I was trying to index the blob content to Azure search. I added blob content to the search index through blob indexer.

I am using MongoDB to store the uploaded file information along with blob path. We have to add some tags to the file which were stored in MongoDB. Now I want to add these tags into Azure search for that file along with file content.

The problem I am facing is,

Problem 1: To maintain the uniqueness(search key field) between MongoDB record and blob indexer. Initially, I want to use the metadata_storage_path from blob indexer and the base64 encoded blob path which I was stored in MongoDB. But the problem is it never matches the metadata_storage_path and base64 encoded blob path from my node.js.

Problem 2: TO solve the Problem 1, I came into another approach to store my MongoDB file id(FID) as a custom metadata field to the blob to get the uniqueness(search key field) for search index and mongoDB record. The problem here how can I map the custom metadata field to key field? I am not able to index the blob custom metadata fields.

In both the scenarios I am not able to achieve the expected results. How can I achieve the search index key field between MongoDB and Azure blob?

You can use base64 encoded blob path as the document key, which you can get in both indexers by using base64 field mapping. Check https://learn.microsoft.com/en-us/azure/search/search-indexer-field-mappings#base64EncodeFunction for all the options to match your node.js encoding function.
