# Natural Language Search restaurants

This demo restaurant search showcases the **Natural Language Search** feature of Typesense. This allows users to type a free-form sentence into the search bar. Typesense then leverages **Large Language Models** (LLMs) to understand users' intent, automatically translating the natural language query into structured search parameters like filters, sort orders, and relevant keywords.

This implementation uses **Next.js 14 App Router** for the front end, [typesense-js](https://github.com/typesense/typesense-js) client SDK for sending queries to Typesense, [TanStack query](https://tanstack.com/query/latest) for infinite scroll pagination, and [gemini-2.5-flash-lite](https://docs.cloud.google.com/vertex-ai/generative-ai/docs/models/gemini/2-5-flash-lite) as the natural language search model.
