Future work: add MongoDB Atlas Search Index tab

Summary

Add a dedicated Search Index tab for MongoDB Atlas connections in Index Management.

PR #732 adds the Index Management experience and is currently focused on the Vector tab for Azure DocumentDB. Atlas uses a separate search index resource model and wire protocol commands, so it should have a separate Search Index tab rather than reuse the DocumentDB Vector tab.

Automatic provider based tab switching is not available yet. This issue tracks that switching behavior and the Atlas Search Index experience as future work.

Proposed scope

• Detect when Index Management is connected to MongoDB Atlas.
• Show a Search Index tab for Atlas instead of the Azure DocumentDB Vector tab.
• Use createSearchIndexes, $listSearchIndexes, updateSearchIndex, dropSearchIndex, and $vectorSearch over the MongoDB wire protocol.
• Preserve Atlas status and queryable as separate lifecycle values.
• Support Atlas vector definitions, filter fields, indexing methods, and quantization through provider specific contracts.
• Do not use the Atlas Administration REST API.

Context

Related PR: #732

The current implementation plan remains focused on Azure DocumentDB vector indexes. We will return to Atlas Search Index support and prioritize it based on customer requests.

Triage

This is future work and needs product and engineering triage.

Start by reviewing PR #732 and the existing Index Management experience, then identify where provider detection and the Azure DocumentDB Vector tab are handled. Done means Atlas connections show a separate Search Index tab using the listed MongoDB wire protocol commands, with the specified lifecycle and provider-specific index behavior; product and engineering triage is still needed first.
