doc1.put("content", "<h1>Title</h1><p>Content 1</p>");
        documents.add(doc1);

        final Map<String, Object> doc2 = new HashMap<>();
        doc2.put("title", "Doc 2");
        doc2.put("content", "<ul><li>Item A</li><li>Item B</li></ul>");
        documents.add(doc2);

        final String result = client.testBuildContext(documents);
        assertTrue(result.contains("TitleContent 1"));

**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**

```bash
curl -X PUT "http://localhost:8080/api/admin/documents/bulk" \
