Attention:
This implementation starts an asyncio event loop which
will only work if running in a sync env. In an async env, it should
fail since there is already an event loop running.
This code should be updated to kick off the event loop from a separate
thread if running within an async context.
load_and_split(text_splitter: Optional[TextSplitter] = None) → List[Document]¶
Load Documents and split into chunks. Chunks are returned as Documents.
Parameters
text_splitter – TextSplitter instance to use for splitting documents.
Defaults to RecursiveCharacterTextSplitter.
Returns
List of Documents.
