langchain.text_splitter.RecursiveCharacterTextSplitter¶
- class langchain.text_splitter.RecursiveCharacterTextSplitter(separators: Optional[List[str]] = None, keep_separator: bool = True, is_separator_regex: bool = False, **kwargs: Any)[source]¶
Splitting text by recursively look at characters.
Recursively tries to split by different characters to find one that works.
Create a new TextSplitter.
