     """Get cached extraction results for specific chunk IDs
 
+    This function retrieves cached LLM extraction results for the given chunk IDs and returns
+    them sorted by creation time. The results are sorted at two levels:
+    1. Individual extraction results within each chunk are sorted by create_time (earliest first)
+    2. Chunks themselves are sorted by the create_time of their earliest extraction result
+
     Args:
         llm_response_cache: LLM response cache storage
         chunk_ids: Set of chunk IDs to get cached results for
-        text_chunks_data: Pre-loaded chunk data (optional, for performance)
-        text_chunks_storage: Text chunks storage (fallback if text_chunks_data is None)
+        text_chunks_storage: Text chunks storage for retrieving chunk data and LLM cache references
 
     Returns:
-        Dict mapping chunk_id -> list of extraction_result_text
+        Dict mapping chunk_id -> list of extraction_result_text, where:
+        - Keys (chunk_ids) are ordered by the create_time of their first extraction result
+        - Values (extraction results) are ordered by create_time within each chunk
