Implementing refreshing ingested text

[Maxton-Huff]

I'm adapting the scripts\ingest-data.ts script to take in text rather than PDFs where the text is retrieved from a series of updating Q&A pages. If I run ingest each week or so, would that add the updated version's text onto the old version's text in the vector database, or would it replace what was previously ingested? If it adds onto what was already ingested, is there a way to remove the old ingested text without deleting the pinecone index?
