 # ArkTS-CodeSearch: A Open-Source ArkTS Dataset for Code Retrieval
 
+> **Looking for the improved version?** Please use [ArkTS-CodeSearch-Pro](https://huggingface.co/datasets/hreyulog/arkts-code-docstring-pro). The Pro dataset applies stricter open-source license filtering, keeps only repositories with `stars > 0`, normalizes comments, removes license/copyright headers and code-only docstrings, enforces minimum docstring length, and performs global code/query deduplication. This original dataset is retained for compatibility.
