Hello, I'm using DocumentSummaryIndex to create summaries of all the documents that I have. I have the code that uses an extended BaseExtractor class that would create extra metadata and also have the code that would loop through and append the metadata.
However, I ran into some code that showed that this may be done by sending an extractor into the DocumentSummaryIndex builder summary_index = DocumentSummaryIndex.from_documents(
documents=documents,
transformations=[splitter],
response_synthesizer = response_synthesizer,
extractors=[sentiment_extractor],
) The above code doesn't work; the extractor is never called. Is there a way of doing the above? It's cleaner than the approach I currently have
