If a user searched for "canine" but your database only contained the word "dog," the search failed. It was rigid, literal, and increasingly out of step with how humans actually communicate. Enter Semantic Search . By shifting from keyword matching to conceptual matching, we allow applications to understand the intent and meaning behind a query. When you combine this with the power of Large Language Models (LLMs) like Gemini Nano, you unlock a new architectural pattern: Retrieval-Augmented Generation (RAG) . Even more revolutionary is the fact that we can now do this entirely on-device. No cloud latency, no massive API bills, and total user privacy.…
