Hey @anchit-nishant I think we got a new merge conflict because of a PR was merged, can you please resolve it?

Wouldn't it be good to call it vertex_ai_search?

[anchit-nishant]

Merged.

Vertex AI Search is a an end to end search solution from GCP, where as Vertex AI Vector Search (earlier called as Matching Engine) is a Vector Database provided by GCP. We are using Vector Search (Matching Engine) here

Got it, thanks for clarifying. Then we should name it as vertex_ai_vector_search because users would search google_matching_engine and they will be redirect to vector search docs. It would be confusing, as I myself faced it too.

Updated the code with "vertex_ai_vector_search" nomenclature. The Google API refers it as MatchingEngine hence kept the core functions same. Merged and tested.

Hey @anchit-nishant Thanks for making the change with the name. Can you please add tests for the this new vector_store and also rebase with main as there is a merge conflict? Thanks!
