## Project Overview

Fess is an Enterprise Search Server built on OpenSearch. It's a Java-based web application that crawls and indexes documents from various sources and provides full-text search capabilities.

## Development Commands

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

# Generate DBFlute source code (when schema changes)

            return false;
        }
    }

    @Override
    public void close() {
        if (s3Client != null) {
            s3Client.close();
        }
    }
