**Step 2: Convert to Fess Format**

Transform documents to include Fess required fields. Example transformation script:

```python
import json

with open('documents.json', 'r') as infile, \
     open('fess-documents.json', 'w') as outfile:
    for line in infile:
        doc = json.loads(line)

        # Transform to Fess format
        fess_doc = {
            "url": doc.get("url", ""),

## Common Development Tasks

### Adding a Protocol Client

1. **Implement `CrawlerClient`**:
```java
public class MyClient extends AbstractCrawlerClient {
    @Override

                final ExtractData extractData = extractor.getText(in, params);
                return extractData.getContent();
            } catch (final IOException e) {
                throw new ExtractException("Could not open " + outputFile.getAbsolutePath(), e);
            }
        }
        try {
            return new String(FileUtil.readBytes(outputFile), outputEncoding);
        } catch (final UnsupportedEncodingException e) {
