### 2. Add Custom Dictionaries (Optional)

Create custom dictionary files in: `${fess.dictionary.path}/[lang]/`

Available dictionary types:
- `stopwords.txt` - Words to exclude from indexing
- `stemmer_override.txt` - Custom stemming rules

9. This *path operation function* is not returning dataclasses (although it could), but a list of dictionaries with internal data.

    FastAPI will use the `response_model` parameter (that includes dataclasses) to convert the response.

You can use **type annotations** the same way you would for input data in function **parameters**, you can use Pydantic models, lists, dictionaries, scalar values like integers, booleans, etc.
