**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 = {

      "content_length": {
        "type": "long"
      },
      "created": {
        "type": "date",
        "format": "date_optional_time"
      },
      "timestamp": {
        "type": "date",
        "format": "date_optional_time"
      },
      "expires": {
        "type": "date",
        "format": "date_optional_time"
      },
      "digest": {
        "type": "text",
        "index": false
      },
