## Development Commands

### Setup
```bash
# Download OpenSearch plugins (required before first build)
mvn antrun:run

# Generate DBFlute source code (when schema changes)
mvn dbflute:download  # One-time setup
mvn dbflute:freegen
mvn license:format
```

### Build
```bash
# Standard build
mvn package

# Clean build
mvn clean package

/**
 * Test class for refactoring changes made to Suggester class.
 *
 * Tests cover:
 * - Index alias helper method (getIndicesForAlias)
 * - Edge cases for switchIndex with EXPECTED_INDEX_COUNT
 * - Index lifecycle with refactored methods
 */

3. Add tests
4. Handle resources properly (try-with-resources)
5. Consider thread safety
6. Update JavaDoc

### When Fixing Bugs

1. Write failing test first
2. Understand root cause
3. Minimal changes
4. Verify no regressions

### When Refactoring

1. Preserve behavior
2. Keep tests green
3. Small incremental steps
4. Don't mix with new features
