# Nia Documentation Search

Search across 3000+ packages (npm, PyPI, Crates, Go) and indexed sources for documentation and code examples.

## Usage

### Semantic search in a package
```bash
uv run python -m runtime.harness scripts/mcp/nia_docs.py \
  --package fastapi --query "dependency injection"
```

### Search with specific registry
```bash
uv run python -m runtime.harness scripts/mcp/nia_docs.py \
  --package react --registry npm --query "hooks patterns"
```

### Grep search for specific patterns
```bash
uv run python -m runtime.harness scripts/mcp/nia_docs.py \
  --package sqlalchemy --grep "session.execute"
```

### Universal search across indexed sources
```bash
uv run python -m runtime.harness scripts/mcp/nia_docs.py \
  --search "error handling middleware"
```
