Prompts for index construction already have default ones, the customization is for who wants to try something different, so would recommend to only customize if you have any purpose
And yes, you can customize systemprompt for query engines, through the service context
@Emanuel Ferreira do I need to use the prompt_helper class in some capacity? I just tried to create my first prompt and I got a cryptic ValueError: ValueError: Got a larger chunk overlap (-36) than chunk size (-366), should be smaller. coming from here: C:\anaconda3\envs\kedro_workbench_venv\lib\site-packages\llama_index\text_splitter\token_splitte β
β r.py:57 in __init__ what I dont understand is that my service_context specifies a SentenceWindowNodeParser for chunking, so I'm guessing this chunking is coming from the prompt text?
