- ## Delete Document
- `delete()` method allows you to delete a document previously added to the app.
- ### Usage
- ```python
- from embedchain import App
- app = App()
- forbes_doc_id = app.add("https://www.forbes.com/profile/elon-musk")
- wiki_doc_id = app.add("https://en.wikipedia.org/wiki/Elon_Musk")
- app.delete(forbes_doc_id) # deletes the forbes document
- ```
- <Note>
- If you do not have the document id, you can use `app.db.get()` method to get the document and extract the `hash` key from `metadatas` dictionary object, which serves as the document id.
- </Note>
- ## Delete Chat Session History
- `delete_session_chat_history()` method allows you to delete all previous messages in a chat history.
- ### Usage
- ```python
- from embedchain import App
- app = App()
- app.add("https://www.forbes.com/profile/elon-musk")
- app.chat("What is the net worth of Elon Musk?")
- app.delete_session_chat_history()
- ```
- <Note>
- `delete_session_chat_history(session_id="session_1")` method also accepts `session_id` optional param for deleting chat history of a specific session.
- It assumes the default session if no `session_id` is provided.
