[srinidhi-sat]

Summary

This notebook is for the Oracle AI Agent Memory Hybrid search companion article.

The notebook shows:

• Oracle AI Agent Memory 26.6 setup with SearchStrategy.HYBRID
• Safe database and embedding-model preflight checks
• OracleDBEmbedder configuration with a database-resident embedding model
• Scoped memory retrieval using SearchScope
• Durable memories containing exact identifiers and natural-language context
• A deliberately similar memory set with invoice, customer, renewal, and error-code distractors
• Async hybrid retrieval using memory.search_async(...)
• Five exact, semantic, and mixed-query evaluation scenarios
• Rank-one PASS validation for expected memories
• Production guidance for schema policy and search-index synchronization
