# NLP Service

Lightweight FastAPI service that parses free-text search queries into structured extractions,
replacing Ollama for the Familienarchiv NL search feature.

## Stack

- Python 3.11, FastAPI 0.115, spaCy 3.8, dateparser 1.2

## Endpoints

- `POST /parse` — parse a free-text query, return extraction matching `OllamaExtraction` contract
- `GET /health` — returns `{"status": "ok"}` when all models are loaded

## Running locally

```bash
pip install -r requirements.txt
python -m spacy download de_core_news_sm en_core_web_sm es_core_news_sm
uvicorn main:app --reload --port 8001

curl -X POST http://localhost:8001/parse \
  -H "Content-Type: application/json" \
  -d '{"query": "Briefe von Opa Hermann an Marie vor 1920", "lang": "de"}'
```

## Testing

```bash
pytest -v
```

## Design spec

See `docs/superpowers/specs/2026-06-07-spacy-nlp-service-design.md`.

## Notes

This is a **prototype** for extraction quality evaluation. No docker-compose integration or
Java-side changes in this iteration. The extraction contract matches `OllamaExtraction` in
`backend/src/main/java/org/raddatz/familienarchiv/search/`.
