Multi-Document Agentic RAG
This example provides a comprehensive guide on creating a Multi-Document Agentic RAG leveraging the power of Embeddings and VectorDB. We'll explore how we can use Reasoning + Acting (ReAct) strategy to harness our RAG setup and make it more intelligent using different tools.

Creating relevant Vector Store
We are going to create different lancedb vector stores, each associated with a specific table in a local database (./lancedb). The tables store data related to different aspects of automotive data, which is defined in our json files, such as problems, parts, diagnostics, cost estimates, and maintenance schedules.
[5]
Create the retrievers objects
Retrievers objects are python objects that are used to retrieve the relevant data from the database. Each retriever is specific to the type of data that we want to retrieve.

Creating Function tools and setting up Agent
FunctionTool from LLamaIndex provides a suitable interface for writing functions that can be used as the tools when we set up our Agent. Apart from the core tools, we are going to set up some additional helper tools that uses other tools in abstraction way!

Added user message to memory: My car has 60,000 miles on it. What maintenance should I be doing now, and how much will it cost?
=== Calling Function ===
Calling function: get_maintenance_schedule with args: {"mileage": 60000}
=== Function Output ===
['{"mileage": 510000, "tasks": ["Exhaust system replacement", "Suspension system replacement", "Clutch replacement", "Differential fluid change"], "importance": "Major service", "estimated_time": "6-8 h', '[{"mileage": 30000, "tasks": ["Oil and filter change", "Tire rotation", "Air filter replacement", "Brake inspection"], "importance": "Regular maintenance", "estimated_time": "2-3 hours"}, {"mileage": ']
=== LLM Response ===
At 60,000 miles, you should consider the following maintenance tasks:
1. Exhaust system replacement
2. Suspension system replacement
3. Clutch replacement
4. Differential fluid change
These tasks are part of a major service and are estimated to take 6-8 hours to complete.
For cost estimates, I can provide individual estimates for each task. Would you like me to do that?
