[Advent of Agents] Day 15: Grounding with ADK: Agentic RAG with Vector Search 2.0

[abraha...@google.com]

Hi everyone,

Day 15 of Google's Advent of Agents — Season 2 is now live! 🌸

Build a sophisticated Agentic RAG system in minutes by combining the power of Vertex AI Vector Search 2.0 and the Agent Development Kit. Learn how to move beyond simple retrieval to create agents that parse intent, build structured filters, and orchestrate search workflows autonomously.

Today's Highlights:

• Simplify your stack with Vector Search 2.0’s managed hybrid search and automatic embedding generation.
• Use ADK to turn a single Python function into a tool that enables LLMs to decompose natural language into semantic queries and metadata filters.
• Optimize search relevance by utilizing the Gemini QUESTION_ANSWERING task type for high-quality grounding.
