Integrate Milvus for Shared Knowledge and Serper API Tool

Implement the 'Milvus DB Tool' and 'Web Search Tool' for your agents. The Milvus tool should allow agents to store and retrieve research findings as embeddings, maintaining a shared knowledge base. The Web Search Tool (e.g., using Serper API) should enable agents to query the internet for information on heavy machinery automation. Describe their API interfaces and provide Python code snippets for tool integration within CrewAI.
