**Step 2: Format for Fess**

Create NDJSON file with required Fess fields:

```json
{"url":"http://example.com/doc1","title":"Document 1","content":"Full text content...","mimetype":"text/html"}
{"url":"http://example.com/doc2","title":"Document 2","content":"More content...","mimetype":"application/pdf"}
```

**Step 3: Bulk Import**
