TextSplitter

🔹 2. TextSplitter（文本切块器）

示例：

python
复制编辑
from langchain.text_splitter import RecursiveCharacterTextSplitter

splitter = RecursiveCharacterTextSplitter(
    chunk_size=500,
    chunk_overlap=50
)
chunks = splitter.split_documents(docs)

✅ Best Practice：chunk_size 通常设置为 300–800，overlap 设置为 10–100，依任务灵活调整
