# Semantic Search Cache API

This project provides a **semantic search engine with caching and fuzzy clustering**.

It uses:

* Sentence embeddings
* FAISS vector index
* Gaussian Mixture Model clustering
* Semantic caching

The API is built with **FastAPI** and deployed using **Docker** on Hugging Face Spaces.

---

## Features

* Semantic similarity search
* FAISS vector indexing
* Semantic cache for faster repeated queries
* Fuzzy clustering with GMM
* REST API endpoints

---

## API Endpoints

### POST `/query`

Example request:

```json
{
  "query": "space shuttle launch",
  "top_k": 5
}
```

### GET `/cache/stats`

Returns semantic cache statistics.

### DELETE `/cache`

Clears the cache.
