+
+    4. Citation Formatting:
+    - Replaces citations with properly formatted versions.
+    - Adds links if available: [[1]](https://example.com)
+    - Handles cases where links are not available: [[1]]()
+
+    5. Duplicate Handling:
+    - Skips consecutive citations of the same document to avoid redundancy.

+    - Yields DanswerAnswerPiece objects for regular text.
