How to do VectorDB search (with filtering) using the new index lookup?

[KiranS-1952323]

I am building a flow where I need to query the Azure AI Search VectorDB. I have imported and vectorized the PDFs for my project with metadata, including clientID and projectID. Now, in my PromptFlow, I want to query the VectorDB and apply filters. This functionality is available in Azure AI Search but not in PromptFlow (or it is now deprecated). How can I do this?

I am trying to get the old vectorDB working, is this the right path?
